* Merge branch 'for-linus' of git://git.o-hand.com/linux-rpurdie-backlightLinus Torvalds2007-07-22
|\ | | | | | | | | | | | | * 'for-linus' of git://git.o-hand.com/linux-rpurdie-backlight: leds: cr_bllcd.c: build fix backlight: Convert from struct class_device to struct device backlight: Fix order of Kconfig entries
| * backlight: Convert from struct class_device to struct deviceRichard Purdie2007-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Convert the backlight and LCD classes from struct class_device to struct device since class_device is scheduled for removal. One nasty API break is the backlight power attribute has had to be renamed to bl_power and the LCD power attribute has had to be renamed to lcd_power since the original names clash with the core. I can't see a way around this. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>

It's complaining that we dereference 'edge_port' in line 2799 which makes the test of that pointer against NULL in 2800 pointless, since if edge_port was actually NULL we'd have crashed already before reaching line 2800. Reading the edge_open() function it seems to me that the pointer returned by usb_get_serial_port_data(serial->port[i]) and stored in 'edge_port' can never actually be NULL here, so the test is entirely superfluous (even if it could be NULL it would be pointless here, ignoring the then possible crash in that case, since both edge_buf_free() and kfree() can handle being passed NULL pointers.

| * | USB: fix warning caused by autosuspend counter going negativeAlan Stern2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as937) fixes a minor bug in the autosuspend usage-counting code. Each hub's usage counter keeps track of the number of unsuspended children. However the current driver increments the counter after registering a new child, by which time the child may already have been suspended and caused the counter to go negative. The obvious solution is to increment the counter before registering the child.

| * | USB: add "descriptors" binary sysfs attributeAlan Stern2007-07-19

The attribute contains the device descriptor followed by the raw descriptor entry (config plug subsidiary descriptors) for the current configuration. Having this information available in fixed-format binary makes life a lot easier for user programs by avoiding the need to open, read, and parse multiple sysfs text files. The information in this attribute file is much like that in usbfs's device file, but there are some significant differences: The 2-byte fields in the device descriptor are left in little-endian byte order, as they appear on the bus and in the kernel. Only one raw descriptor set is presented, that of the current configuration. Opening this file will not cause a suspended device to be autoresumed. The last item in particular should be a big selling point for libusb, which currently forces all USB devices to be resumed as it scans the device tree.

The status of a completed URB is kept in a local variable and copied to urb->status only when the URB is about to be given back. -EREMOTEIO error status for control transfers is set after the status stage rather than when the short packet arrives. Some unnecessary uses of urb->lock are removed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: Olav Kongas <ok@artecdesign.ee> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found the first regresson in the rewritten ("all dynamic" and "no races") driver. If application uses O_NONBLOCK, I return -EAGAIN despite the URB being submitted successfuly. This causes the application to resubmit the same data erroneously. The fix is to pretend that the transfer has succeeded even if URB was merely queued. It is the same behaviour as with the old version.

* | dev_vdbg(), available with -DVERBOSE_DEBUGDavid Brownell2007-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This defines a dev_vdbg() call, which is enabled with -DVERBOSE_DEBUG. When enabled, dev_vdbg() acts just like dev_dbg(). When disabled, it is a NOP ... just like dev_dbg() without -DDEBUG. The specific code was moved out of a USB patch, but lots of drivers have similar support. That is, code can now be written to use an additional level of debug output, selected at compile time. Many driver authors have found this idiom to be very useful. A typical usage model is for "normal" debug messages to focus on fault paths and not be very "chatty", so that those messages can be left on during normal operation without much of a performance or syslog load. On the other hand "verbose" messages would be noisy enough that they wouldn't normally be enabled; they might even affect timings enough to change system or driver behavior.
