Hi all,
On merging --- it would seem everyone is happy with merging this
through the drm-misc tree. The last patch should wait until all
users are gone for sure, probably to the next kernel release.
There are no users of drm_get_format_name() in linux-next
currently after the 3rd patch.
This set adds support for %p4cc printk modifier for printing V4L2 and DRM
fourcc codes. The codes are cumbersome to print manually and by adding the
modifier, this task is saved from the V4L2 and DRM frameworks as well as
related drivers. DRM actually had it handled in a way (see 3rd patch) but
the printk modifier makes printing the format easier even there. On V4L2
side it saves quite a few lines of repeating different implementations of
printing the 4cc codes.
Further work will include converting the V4L2 drivers doing the same. I
left these out from this version since individual drivers are easier
changed without dealing with multiple trees.
Since v8:
- Reduce ternary conditionals in intel_plane_uapi_info().
- Wrap a long line in intel_plane_hw_info().
Since v7:
- Add more examples, one with big endian and another with a space.
- Add Y10 test format.
- Use "0123" in the size string for temporary buffer.
- Added acks.
- Split the 3rd patch into two: driver changes and removal of
drm_get_format_name().
Since v6:
- Don't drop spaces in fourcc codes.
- Print unprintable characters as dot ('.') instead of hexadecimal number
in parentheses.
- Convert DRM from drm_get_format_name() to %p4cc. I wonder if this should
be merged through the DRM tree, albeit it's probably unlikely to
conflict with other changes. Further use of the function could be a
problem.
- Make tests more realistic.
Since v5:
- Added V4L2 core conversion to %p4cc, as well as change the DRM
fourcc printing function to use %p4cc.
- Add missing checkpatch.pl checks for %p4cc modifier.

I've merged patches 1 to 3 into drm-misc-next. Patch 4 (and maybe some
final fix-up patch) will land when all DRM trees have catched up the
changes.
Best regards
