Date: Wed, 27 Mar 2019 14:15:22 -0400 From: Sasha Levin <sashal@...nel.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: Ezequiel Garcia <ezequiel@...labora.com>, Hans Verkuil <hverkuil-cisco@...all.nl>, Mauro Carvalho Chehab <mchehab+samsung@...nel.org>, Sasha Levin <sashal@...nel.org>, linux-arm-kernel@...ts.infradead.org, linux-media@...r.kernel.org Subject: [PATCH AUTOSEL 4.14 058/123] media: s5p-g2d: Correct return type for mem2mem buffer helpers From: Ezequiel Garcia <ezequiel@...labora.com> [ Upstream commit 30fa627b32230737bc3f678067e2adfecf956987 ] 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.
