Subject: [media] media: videobuf2: last_buffer_queued is set at fill_v4l2_buffer()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=dcbc216d33e99692276f0eb9ea508f66df4075bf;p=deliverable%2Flinux.git

[media] media: videobuf2: last_buffer_queued is set at fill_v4l2_buffer()

The location in which last_buffer_queued is set is moved to fill_v4l2_buffer().
So, __vb2_perform_fileio() can use vb2_core_dqbuf() instead of
vb2_internal_dqbuf().
