openwrt/target/linux/bcm27xx/patches-6.6/950-0577-drm-vc4-Fix-FKMS-for-when-the-YUV-chroma-planes-are-.patch
Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0577/1085] drm/vc4: Fix FKMS for when the YUV chroma planes
are different buffers
The code was assuming that it was a single buffer with offsets,
when kmstest uses separate buffers and 0 offsets for each plane.
