This will be useful to write tests that depends on these formats.
ARGB and XRGB follows the a similar implementation of the former formats.
Just adjusting for 16 bits per channel.
V3: Adapt the handlers to the new format introduced in patch 7 V3.
V5: Minor improvements
Added le16_to_cpu/cpu_to_le16 to the 16 bits color read/writes.
Is there something we could add to the DRM's format-conversion helpers? Best regards Thomas
