[d-kernel] [PATCH 0/1] Support Baikal-M in 6.12

[Daniil Gnusarev]

В драйвере baikal-vdu в списке форматов кадрового буфера присутствуют
записи с порядком цветов BGR. Данный порядок не поддерживается
устройством, их необходимо удалить.
Данный патч предназначен для ядер 6.12.

[d-kernel] [PATCH 1/1] drm: baikal-vdu: remove unsupported framebuffer formats

[Daniil Gnusarev]

The VDU block does not support BGR framebuffer formats,
they must be removed from the list of supported ones.
