* - DRM format info specifies depth as the number of color

* bits; including alpha, but not including filler bits.
|

* - Linux' EFI platform code computes lfb_depth from the

* - VBE 1.1 defines lfb_depth for XRGB1555 as 16, but later

* - On the kernel command line, 'bpp' of 32 is usually

* XRGB8888 including the filler bits, but 15 is XRGB1555
|
||||
* not including the filler bit.
|

*
|

* It's not easily possible to fix this in struct screen_info,

* as this could break UAPI. The best solution is to compute

* bits_per_pixel here and ignore lfb_depth. In the loop below,
