media: v4l2-mem2mem: Correct return type for mem2mem buffer helpers
This commit changes the return 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
which currently return void pointer.
In every case, the actual return type is a struct vb2_v4l2_buffer
pointer. Change the return type of the listed functions,
so type checking can be properly used.
