Geert Uytterhoeven f30e27779d drm/fb-helper: Round up bits_per_pixel if possible ... When userspace requests a video mode parameter value that is not supported, frame buffer device drivers should round it up to a supported value, if possible, instead of just rejecting it. This allows applications to quickly scan for supported video modes. Currently this rule is not followed for the number of bits per pixel, causing e.g. "fbset -depth N" to fail, if N is smaller than the current number of bits per pixel. Fix this by returning an error only if bits per pixel is too large, and setting it to the current value otherwise. See also Documentation/fb/framebuffer.rst, Section 2 (Programmer's View of /dev/fb*").
