| * [media] staging/lirc: fix mem leaks and ptr err usageJarod Wilson2011-01-19
| | | | | | | | | | | | | | | | | | | | | | When the lirc drivers were converted over to using memdup_user, I mistakenly also removed corresponding calls to kfree. Add those back. I also screwed up on the allocation error check in lirc_serial, using if (PTR_ERR()) instead of if (IS_ERR()), which broke transmit.

| * [media] hdpvr: reduce latency of i2c read/write w/recycled bufferJarod Wilson2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current hdpvr code kmalloc's a new buffer for every i2c read and write. Rather than do that, lets allocate a buffer in the driver's device struct and just use that every time. The size I've chosen for the buffer is the maximum size I could ascertain might be used by either ir-kbd-i2c or lirc_zilog, plus a bit of padding (lirc_zilog may use up to 100 bytes on tx, rounded that up to 128). Note that this might also remedy user reports of very sluggish behavior of IR receive with hdpvr hardware. v2: make sure (len <= (dev->i2c_buf)) [Jean Delvare] Reported-by: Jean Delvare <khali@linux-fr.org> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * [media] hdpvr: enable IR partJarod Wilson2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of things going on here, but the end result is that the IR part on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or lirc_zilog. First up, there are some conditional build fixes that come into play whether i2c is built-in or modular. Second, we're swapping out i2c_new_probed_device() for i2c_new_device(), as in my testing, probing always fails, but we *know* that all hdpvr devices have a z8 chip at 0x70 and 0x71. Third, we're poking at an i2c address directly without a client, and writing some magic bits to actually turn on this IR part (this could use some improvement in the future). Fourth, some of the i2c_adapter storage has been reworked, as the existing implementation used to lead to an oops following i2c changes c. 2.6.31. Earlier editions of this patch have been floating around the 'net for a while, including being patched into Fedora kernels, and they *do* work. This specific version isn't yet tested, beyond loading ir-kbd-i2c and confirming that it does bind to the RX address of the hdpvr. [mchehab@redhat.com: I2C_CLASS_TV_ANALOG is not defined.

| * [media] rc/mceusb: timeout should be in ns, not usJarod Wilson2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | Fixes an egregious bug in mceusb driver, where the receiver was being put into idle mode far sooner than it should have, thanks to storing a timeout value that in us where it should be ns. Basically, the receiver kept going into idle mode before a trailing space had been fully received, which was causing problems for some protocols, most notably manifesting as lirc userspace never receiving a trailing space for any rc5 signals.

| * [media] v4l2-device: fix 'use-after-freed' oopsHans Verkuil2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a bug in v4l2_device_unregister where the sd pointer can be dereferenced after it was freed. Normally the i2c adapter is removed before this function is called. Removing the adapter will also unregister all subdevs on that adapter, so generally v4l2_device_unregister has nothing to do. However, in the case of a platform i2c bus that bus is generally not freed. In that case, after freeing the i2c subdevice the code will fall into the second block when it tests if the subdev is a SPI device. But by that time the subdev is already freed and the kernel oopses. The fix is trivial: continue with the loop after freeing the i2c or spi subdevice.

| | | | | | | | | | | | | | | | | | | | | | Zeroing video_device.dev causes a memory leak if video_set_drvdata was called before video_register_device was called. video_set_drvdata calls dev_set_drvdata which allocates video_device.dev.p. memsetting this will prevent freeing of that memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IR Rx polling thread was originally a kernel_thread long ago, and had only been minimally converted to a kthread. This patch finishes that conversion by - cleaning up all the unneeded completions - destroying the kthread properly by calling kthread_stop() - changing lirc_thread() to test kthread_should_stop() just before every point where it may sleep - reorganizing the lirc_thread() function so it uses fewer lines - modifying the name of the kthread from "lirc_zilog" to "zilog-rx-i2c-N", so ps will show which kthread polls which Zilog Z8 IR unit. Also some minor tweaks were made to logging emitted by the ir_probe() function. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * [media] lirc_zilog: Extensive rework of ir_probe()/ir_remove()Andy Walls2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is an extensive rework of the ir_probe() and ir_remove() functions. It removes all the double binding and allocation problems on module load. It removes almost all the memory leaks on module exit and on device instantiation failure. Proper destruction of the Rx polling kthread still needs investigation and more work, but it is no worse than it already was. This rework also had side effects that include: - encapsulation of the ir_devices[] array - serialization of access to the ir_devices[] array - semantic change of the module parameter "disable_rx" to "tx_only" If tx_only is true, the module does not claim the i2c_client for the IR Rx function, and only claims and handles the i2c_client for the IR Tx function. This is a first step in providing the option of letting ir-kbd-i2c.c handle IR Rx function, while lirc_zilog handles the IR Tx function.

| * [media] lirc_zilog: Split struct IR into structs IR, IR_tx, and IR_rxAndy Walls2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is a mostly mechanical break of the main struct IR data structure into common, Rx, and Tx structures. There were some small logical changes required as well, such as eliminating "is_hdpvr", to accomplish this. This change is an intiial step in reworking lirc_zilog to decouple the Rx and Tx handling as much as possible to fit with the new I2C binding model. This change actually makes lirc_zilog a little more broken than it already was - memory deallocation in particular got worse. However, this change makes the remaining problems easier to see and address. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi, While reading drivers/media/video/tlg2300/pd-video.c::alloc_bulk_urbs_generic() I noticed that - We don't free the memory allocated to 'urb' if the call to usb_alloc_coherent() fails. - If the 'num' argument to the function is ever <= 0 we'll return an uninitialized variable 'i' to the caller. The following patch addresses both of the above by a) calling usb_free_urb() when usb_alloc_coherent() fails and by explicitly initializing 'i' to zero. I also moved the variables 'mem' and 'urb' inside the for loop. This does not actually make any difference, it just seemed more correct to me to let variables exist only in the innermost scope they are used.

| | | | | | | | | | | | | | | | | | | | | | | | Renamed has_new to is_new. Drivers can use the is_new field to determine if a new value was specified for a control. The v4l2_ctrl_handler_setup() must always set this to 1 since the setup has to force a full update of all controls.

| * [media] v4l2-subdev: add (un)register internal opsHans Verkuil2011-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some subdevs need to call into the board code after they are registered and have a valid struct v4l2_device pointer. The s_config op was abused for this, but now that it is removed we need a cleaner way of solving this. So this patch adds a struct with internal ops that the v4l2 core can call. Currently only two ops exist: register and unregister. Subdevs can implement these to call the board code and pass it the v4l2_device pointer, which the board code can then use to get access to the struct that embeds the v4l2_device. It is expected that in the future open and close ops will also be added.
