The ffz() return value is undefined if the instance mask does not contain any zeros. If it returned 32, the following set_bit would corrupt the debugfs_root pointer. Switch to IDA for context index allocation. This also removes the artificial 32 instance limit for all except CodaDx6. Signed-off-by:

Swapping the order between v4l2 subdevice registration and checking chip id in b7a41762 ("media: ov2680: don't register the v4l2 subdevice before checking chip ID") makes the mode restore to use the sensor controls before they are set, so move the mode restore call to s_power after the handler setup for controls is done. This remove also the need for the error code path in power on function. Fixes: b7a41762 ("media: ov2680: don't register the v4l2 subdevice before checking chip ID") Signed-off-by:

The H3 has a slightly different CSI controller (no BT656, no CCI) which looks a lot like the original A31 controller. Add a compatible for the A31, and more specific compatible the for the H3 to be used in combination for the A31. Reviewed-by:

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:
