Stop the URBs in em28xx_stop_streaming(), so that em28xx_irq_callback() cannot be called after the streaming has stopped. This should eliminate the crashes reported by Antti Palosaari and the warnings reported by Andy Furniss. Signed-off-by:

This patch removes the non-required spinlock acquire/release calls on 'queue_irqlock' from 'uvc_queue_next_buffer' routine. This routine is called from 'video->encode' function (which translates to either 'uvc_video_encode_bulk' or 'uvc_video_encode_isoc') in 'uvc_video.c'. As, the 'video->encode' routines are called with 'queue_irqlock' already held, so acquiring a 'queue_irqlock' again in 'uvc_queue_next_buffer' routine causes a spin lock recursion. Signed-off-by:

copy_in_user() already checks for write permission, so we don't need to do it here. This was added in 1a5e4c86 "[media] uvcvideo: Implement compat_ioctl32 for custom ioctls". Signed-off-by:

This patch removes BUG_ON in ir_raw_event_thread which IMO is a over-kill, and this kills the ir_raw_event_thread too. With a bit of additional logic in this patch, we nomore need to kill this thread. Other disadvantage of having a BUG-ON is, wake_up_process(dev->raw->thread) called on dead thread via ir_raw_event_handle will result in total lockup in SMP system. Advantage of this patch is ir-raw event thread is left in a usable state even if the fifo does not have enough bytes. This patch sets the thread into TASK_INTERRUPTIBLE if raw-fifo has less then sizeof(struct ir_raw_event) bytes. Signed-off-by:

The lirc sasem and imon drivers now use the module_usb_driver macro, so the old init/exit function prototypes are useless. This patch eliminates this warnings: media_build/v4l/lirc_imon.c:74:19: warning: 'imon_init' declared 'static' but never defined [-Wunused-function] media_build/v4l/lirc_imon.c:75:20: warning: 'imon_exit' declared 'static' but never defined [-Wunused-function] media_build/v4l/lirc_sasem.c:84:19: warning: 'sasem_init' declared 'static' but never defined [-Wunused-function] media_build/v4l/lirc_sasem.c:85:20: warning: 'sasem_exit' declared 'static' but never defined [-Wunused-function] Signed-off-by:

In this driver there are several entities associated with separate platform or I2C client devices, which may get probed in random order. When the platform device bound to the media device driver is probed all other entity drivers need to be already in place and initialized. If any of them is not, fail the media device probe and return an error indicating we need to be retried once any new driver gets registered. The media device driver probe will not succeed until there are available all needed sub-drivers, as specified in the platform data. While at it, make sure the s5p-csis module (MIPI-CSI receiver driver) does not get unloaded when in use, by guarding its usage with try_module_get/module_put. This patch is a prerequisite for adding the device tree support. It now also allows again to unbind/bind the driver at runtime from user space via sysfs. Signed-off-by:

This patch prevents blocking on DQBUF at a video capture node in some conditions, after STREAOMOFF/STREAMON sequence. The ST_CAPT_SUSPEND flag should not be set during normal stream off, otherwise the capture engine is not properly enabled at stream on. Reported-by:

The MIPI-CSI2 data alignment parameter can be derived from media bus pixel code, so it can be now dropped from the platform data structure. This is a prerequisite for adding the device tree support. Once this patch is merged the corresponding fields will be removed from the drivers' public headers and corresponding board files. Signed-off-by:

Add support for VIDIOC_SUBDEV_S_SELECTION and VIDIOC_SUBDEV_G_SELECTION IOCTLs. They replace functionality provided by VIDIOC_SUBDEV_S_CROP and VIDIOC_SUBDEV_G_CROP IOCTLs and also add new functionality (composing). VIDIOC_SUBDEV_G_CROP and VIDIOC_SUBDEV_S_CROP continue to be supported. Signed-off-by:

There was a bug I2C adapter writes and reads one byte too much. As the most I2C clients has auto-increment register addressing this leads next register from the target register overwritten by garbage data. As a change remove whole register address byte usage and write data directly to the I2C bus without saying what are register address bytes to firmware. Signed-off-by:
