Re: [Linux-fbdev-devel] [PATCH] cirrusfb: fix color component length for pseudocolor modes

cirrusfb incorrectly sets the length of the color fields to 6 bits
for PSEUDOCOLOR modes, even though 8 bits are always used per pixel.
Fix this by setting the length to 8.

This is already fixed in the -mm tree (cirrusfb-check_var-improvements.patch).
