Subject: [PATCH] mm-video-v4l2: Squash below changes
|
|
|
|
mm-video-v4l2: Protect buffer access and increase input buffer size
|
|
|
|
Protect buffer access for below scenarios:
|
|
*Increase the scope of buf_lock in free_buffer to avoid access
|
|
of freed buffer for both input and output buffers. Also, add check
|
|
before output buffer access.
|
|
*Disallow allocate buffer mode after client has called use buffer.
|
|
Allocate additional 512 bytes of memory for input buffers on top of
|
|
allocation size as per hardware requirement.
|
|
|
|
mm-video-v4l2: correct the buffer error flag setting
|
|
|
|
The buffer error flag setting is corrected in free_buffer()

|
