| | | | | | | | | | | | | | | | | | | | | | The multifrontend changes on cx88 assumed that all boards that use cx88-mpeg supports DVB. This is not true.

| * V4L/DVB (9331): Remove unused inode parameter from video_ioctl2Mauro Carvalho Chehab2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | inode is never used on video_ioctl2. Remove it and rename the function to __video_ioctl2. This allows its usage directly as a callback at fops.unlocked_ioctl. Since we still need a callback with inode to be used with fops.ioctl, this patch adds video_ioctl2() that is just a call to __video_ioctl2(). Also, this patch adds some comments about video_ioctl2 and __video_ioctl2 usage at v4l2-ioctl.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | The inode parameter at v4l_compat_translate_ioctl() were just passed over several places just to keep compatible with fops.ioctl. However, it weren't used anywere. This patch gets hid of this unused parameter.

| * V4L/DVB (9327): v4l: use video_device.num instead of minor in video%dHans Verkuil2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

| * V4L/DVB (9300): pvrusb2: Fix deadlock problemMike Isely2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix deadlock problem in 2.6.27 caused by new USB core behavior in response to a USB device reset request. With older kernels, the USB device reset was "in line"; the reset simply took place and the driver retained its association with the hardware. However now this reset triggers a disconnect, and worse still the disconnect callback happens in the context of the caller who asked for the device reset. This results in an attempt by the pvrusb2 driver to recursively take a mutex it already has, which deadlocks the driver's worker thread. (Even if the disconnect callback were to happen on a different thread we'd still have problems however - because while the driver should survive and correctly disconnect / reconnect, it will then trigger another device reset during the repeated initialization, which will then cause another disconect, etc, forever.) The fix here is simply to not attempt the device reset (it was of marginal value anyway). Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| * | | | dm: remove unused flush_allKiyoshi Ueda2008-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the DM_WQ_FLUSH_ALL state that is unnecessary. The dm_queue_flush(md, DM_WQ_FLUSH_ALL, NULL) in dm_suspend() is never invoked because: - 'goto flush_and_out' is the same as 'goto out' because the 'goto flush_and_out' is called only when '!noflush' - If r is non-zero, then the code above will invoke 'goto out' and skip this code. No functional change.
