Subject: [PATCH 4.4 039/168] media: s5p-jpeg: Correct return type for mem2mem buffer helpers
[ Upstream commit 4a88f89885c7cf65c62793f385261a6e3315178a ]
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.
