4.14-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 43c145195c7fc3025ee7ecfc67112ac1c82af7c2 ]
Fix the assigned type of mem2mem buffer handling API.
Namely, these functions:
v4l2_m2m_next_buf
v4l2_m2m_last_buf
v4l2_m2m_buf_remove
v4l2_m2m_next_src_buf
v4l2_m2m_next_dst_buf
v4l2_m2m_last_src_buf
v4l2_m2m_last_dst_buf
v4l2_m2m_src_buf_remove
v4l2_m2m_dst_buf_remove
return a struct vb2_v4l2_buffer, and not a struct vb2_buffer.
Fixing this is necessary to fix the mem2mem buffer handling API,
changing the return to the correct struct vb2_v4l2_buffer instead
of a void pointer.
