This is a reboot of this old patch: https://patchwork.kernel.org/patch/9961789/ I've taken Sakari's suggestion and made new patches. It happens too often that we want to log a fourcc, either in kernel or in userspace, so I think this will be quite useful. Regards, Hans Hans Verkuil (2): videodev2.h: add macros to print a fourcc v4l2-ioctl.c: use new V4L2_FOURCC_CONV/ARGS macros drivers/media/v4l2-core/v4l2-ioctl.c | 8 ++------ include/uapi/linux/videodev2.h | 13 +++++++++++++ 2 files changed, 15 insertions(+), 6 deletions(-) -- 2.20.1
