From: Antonino A. Daplas Date: Tue, 31 Jul 2007 07:37:36 +0000 (-0700) Subject: fbdev: Fix logo if logo depth is less than framebuffer depth X-Git-Tag: v2.6.23-rc2~132 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=1692b37c99d5087cf2f814466a907a3dd35a1453;p=linux-2.6-omap-h63xx.git fbdev: Fix logo if logo depth is less than framebuffer depth The VGA16 logo (bpp = 4) and monochrome logo (bpp = 1) do not contain any color information (no CLUT). If the fb depth is > logo depth, these logo's will not properly display. Fix by using the console palette instead of creating a new one.
