Subject: [PATCH] fbdev: Use logo with depth of 4 or less for static pseudocolor
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=397eeab321e87d8c1ef928b58f256513e6f481dc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] fbdev: Use logo with depth of 4 or less for static pseudocolor

Since the visual STATIC_PSEUDOCOLOR has a read-only colormap, use logos
with 16 colors only since these logos use the console palette.  This has a
higher likelihood that the logo will display correctly.
