Subject: [PATCH 0858/1085] drivers: media: pisp_be: Update seqeuence numbers
|
||
|
|
of the buffers
|
||
|
|
|
||
|
|
Add a framebuffer sequence counter and increment on every completed job.
|
||
|
|
This counter is then used to update the VB2 buffer sequence count before
|
||
|
|
calling vb2_buffer_done().
|
||
|
