Subject[PATCH 4.19 087/187] media: rockchip/rga: Correct return type for mem2mem buffer helpers
Date
4.19-stable review patch.  If anyone has any objections, please let me know.

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

[ Upstream commit da2d3a4e4adabc6ccfb100bc9abd58ee9cd6c4b7 ]

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.
