They also provide secondary USB interfaces that talk the Qualcomm Diagnostic Monitor (QCDM) protocol which can be used for status and strength. Make those QCDM ports accessible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've got a trivial patch for the pl2303 driver, that's what I needed to make the wacom serial tablet driver work properly. It uses the TIOCGSERIAL ioctl to determine if it's talking to a serial device or not, which I gather is rather common, but the pl2303 driver didn't implement that ioctl. Here's a patch, I'm not sure it's absolutely correct, I mostly looked at other similar usbserial drivers to see what I must do, but it works for me.

| * | usb-storage: use max_hw_sectors instead of max_sectorsAlan Stern2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1347) makes some adjustments to the way usb-storage handles the request-queue parameters. USB host controllers are able to handle arbitrarily long scatter-gather lists, since they are limited only by main memory and not by the controller hardware. Hence the sg_tablesize field in the host template can be increased to the maximum value. Drivers like usb-storage aren't supposed to touch the queue's max_sectors parameter; instead they are supposed to use the max_hw_sectors value. Accordingly, the patch replaces calls of queue_max_sectors() with calls of queue_max_hw_sectors(). Oddly enough, the blk_queue_max_sectors() routine is nevertheless still appropriate. The existing code imposes a limit of SCSI_DEFAULT_MAX_SECTORS (1024) on the values accepted by the max_sectors attribute file. There's no reason not to accept larger values, so the limit is removed. (It would be nice to change the file's name to max_hw_sectors, but the old name is already a well-established API.)

The fix is using dbgp_pid_write_update() and dbgp_pid_read_update(). 2) The delay loop for waiting for a transaction was not long enough to always complete the initial handshake inside dbgp_wait_until_done(). After the initial handshake the maximum delay length is never reached. The combined result of these two changes allows for the removal of the forced resynchronization where a bulk write was issued with a dummy data payload only to get the device to start accepting data writes again.

| * | USB: isp1760: Flush the D-cache for the pipe-in transfer buffersCatalin Marinas2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the HDC driver writes the data to the transfer buffers it pollutes the D-cache (unlike DMA drivers where the device writes the data). If the corresponding pages get mapped into user space, there are no additional cache flushing operations performed and this causes random user space faults on architectures with separate I and D caches (Harvard) or those with aliasing D-cache.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As Alan Cox have pinpointed the driver still required protection against parallels calls to the config ioctl(). If lock is still necessary the use of BKL is abused here. So replace BKL with a more convenient mutex.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mass storage function responded needlessly to a set configuration packet. This was a leftover from converting gadget (file storage gadget) into a composite function. Moreover, it has failed to respond to get max LUN request. Adding request queueing made the function work better.

| * | USB: mass_storage: eject LUNs on thread exitMichal Nazarewicz2010-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a fallback which forces all LUNs ejection (including non-removable and with prevent_medium_removal flag) when mass storage function (MSF) worker thread exits and gadget fails to handle the situation. Previously, if thread_exits was not specified mass storage function (MSF) did nothing when exiting thread as it's unclear for *function* what to do when it's thread terminates so responsibility of handling this situation was left to the *gadget* using the function. The g_mass_storage handled the situation by unregistering itself (the same thing that file storage gadget does). However, g_multi did nothing and so MSF did not eject LUNs which prevented file system unmounting.
