Subject[PATCH 5.0 119/246] media: rockchip/vpu: Correct return type for mem2mem buffer helpers
Date
5.0-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 29701c3612fa025d5e8dc64c7a4ae8dc4763912e ]

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.
