Zhang Shurong e32b0ad436 fbdev: fix potential OOB read in fast_imageblit() ... [ Upstream commit c2d22806ae ] There is a potential OOB read at fast_imageblit, for "colortab[(*src >> 4)]" can become a negative value due to "const char *s = image->data, *src". This change makes sure the index for colortab always positive or zero.
