From 9af469c5be3b031e651ca90ea193f09bae0792d3 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 8 Feb 2019 11:17:40 -0500 Subject: media: mtk-mdp: Correct return type for mem2mem buffer helpers 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.
