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.

Hi,

aside from the comments I already gave on the other patch adding the
*RGB8888 variants that apply here too, this looks good to me, with or
without those changes.

Is there something we could add to the DRM's format-conversion helpers?

I don't believe there's anything reusable.

Correct if I'm wrong, but from what I understood, these 
format-conversion functions don't seem compatible. The Vkms functions 
are converting to/from an internal format (struct pixel_argb_u16) while 
the functions from `drm_format_helper.c` are converting between two DRM 
formats.

I don't think these vkms format functions are useful to other drivers.
