of_parse_phandle() returns the device node with refcount incremented. There are two nodes that are used temporary in mtk_vcodec_init_enc_pm(), but their refcounts are not decremented.

The video device release() callback for video-i2c driver frees the whole struct video_i2c_data. If there is no user left for the video device when video_unregister_device() is called, the release callback is executed. However, in video_i2c_remove() some fields (v4l2_dev, lock, and queue_lock) in struct video_i2c_data are still accessed after video_unregister_device() is called. This fixes the use after free by moving the code from video_i2c_remove() to the release() callback. Fixes: 5cebaac6 ("media: video-i2c: add video-i2c driver") Reviewed-by:

The Xbox DVD Movie Playback Kit is a USB dongle with an IR remote for the Original Xbox. Historically it has been supported by the out-of-tree lirc_xbox driver, but this one has fallen out of favour and was just dropped from popular Kodi (formerly XBMC) distributions. This driver is heavily based on the ati_remote driver where all the boilerplate was taken from - I was mostly just removing code. Signed-off-by:

This patch adds support to the CEC device implemented with a STM32 microcontroller in X86 SECO Boards, including UDOO X86. The communication is achieved via Braswell integrated SMBus (i2c-i801). The driver use direct access to the PCI addresses, due to the limitations of the specific driver in presence of ACPI calls. The basic functionalities are tested with success with cec-ctl and cec-compliance. Inspired by cros-ec-cec implementation, attaches to i915 driver cec-notifier. Signed-off-by:

Replace g/s_crop by g/s_selection and set the V4L2_FL_QUIRK_INVERTED_CROP flag since this is one of the old drivers that predates the selection API. Those old drivers allowed g_crop when it really shouldn't have since g_crop returns a compose rectangle instead of a crop rectangle for the CAPTURE stream, and vice versa for the OUTPUT stream.

If g_selection is implemented, then the v4l2-ioctl cropcap code assumes that cropcap just implements the pixelaspect part and that g_selection provides the crop bounds and default rectangles. There are still some drivers that only implement cropcap and not g_selection. Split up cropcap into a cropcap and g_selection for those drivers. Signed-off-by:

Some old Samsung drivers use the legacy crop API incorrectly: the crop and compose targets are swapped. Normally VIDIOC_G_CROP will return the CROP rectangle of a CAPTURE stream and the COMPOSE rectangle of an OUTPUT stream. The Samsung drivers do the opposite. Note that these drivers predate the selection API. If this 'QUIRK' flag is set, then the v4l2-ioctl core will swap the CROP and COMPOSE targets as well. That way backwards compatibility is ensured and we can convert the Samsung drivers to the selection API. Signed-off-by:
