Beginning with the commit in the subject, I get the following build error: CC [M] drivers/media/v4l2-core/videobuf2-core.o drivers/media/v4l2-core/videobuf2-core.c: In function ‘vb2_warn_zero_bytesused’: drivers/media/v4l2-core/videobuf2-core.c:1253:2: error: implicit declaration of function ‘__WARN’ [-Werror=implicit-function-declaration] __WARN(); ^ cc1: some warnings being treated as errors My .config is attached. This problem has been bisected to the following commit: commit 77a3c6fd90c94f635edb00d4a65f485687538791 Author: Laurent Pinchart <laurent.pinchart+rene...@ideasonboard.com> Date: Fri Jun 19 08:50:07 2015 -0300 [media] vb2: Don't WARN when v4l2_buffer.bytesused is 0 for multiplanar buffers Commit f61bf13b6a07 ("[media] vb2: add allow_zero_bytesused flag to the vb2_queue struct") added a WARN_ONCE to catch usage of a deprecated API using a zero value for v4l2_buffer.bytesused. However, the condition is checked incorrectly, as the v4L2_buffer bytesused field is supposed to be ignored for multiplanar buffers. This results in spurious warnings when using the multiplanar API. Fix it by checking v4l2_buffer.bytesused for uniplanar buffers and v4l2_plane.bytesused for multiplanar buffers.
