 There is a test in tgafb_mono_imageblit() for a colour image with a 
fall-back to cfb_imageblit().  The test is not necessary as the only 
caller, which is tgafb_imageblit(), checks it too and only invokes this 
function for monochrome images.  It looks like a left-over from before 
some changes to tgafb_imageblit().

Signed-off-by: Maciej W. Rozycki <>
 Checked with and at the run time with an 8-bit TC frame
buffer on a MIPS host.

 Please apply.
