Revert "media: videobuf2-core: don't call memop 'finish' when queueing"
This reverts commit 9ac47200b51cb09d2f15dbefa67e0412741d98aa.
This commit fixes a bug in upstream commit a136f59c0a1f ("vb2: Move
buffer cache synchronisation to prepare from queue") which isn't
present in 4.9.
So as a result you get an UNBALANCED message in the kernel log if
this patch is applied:
vb2: counters for queue ffffffc0f3687478, buffer 3: UNBALANCED!
vb2: buf_init: 1 buf_cleanup: 1 buf_prepare: 805 buf_finish: 805
vb2: buf_queue: 806 buf_done: 806
vb2: alloc: 0 put: 0 prepare: 806 finish: 805 mmap: 0
vb2: get_userptr: 0 put_userptr: 0
vb2: attach_dmabuf: 1 detach_dmabuf: 1 map_dmabuf: 805 unmap_dmabuf: 805
vb2: get_dmabuf: 0 num_users: 1609 vaddr: 0 cookie: 805
Reverting this patch solves this regression.
