[RFC PATCH 1/3] drm: use flags instead of boolean in plane check
Stefan Agner
stefan at agner.ch
Thu Sep 10 09:24:23 UTC 2020
To improve readability and make it easier to add further optional checks
replace the boolean parameters with a single flag bitfield as parameter
of drm_atomic_helper_check_plane_state.
The regular call sites have been converted using a simple coccinelle
patch.

This implements what has been discussed in the thread of the patch
"drm: mxsfb: check framebuffer pitch":
https://lkml.org/lkml/2020/9/8/1342
Before sending it out to all maintainers I wanted to get conformation
if the general approach is fine.
I think in some places there should be another linebreak for the flags,
but this is what coccinelle gives me. Not sure if I should manually fix
those places...
