[PATCH libdrm v2 05/10] util: Store number of colors for indexed formats

[Geert Uytterhoeven]

Store the number of available colors for color-indexed frame
buffer formats in the format_info[] array.  This avoids the need of test
code for having to use switch statements all the time to obtain the
number of colors, or to check if a mode is color-indexed or not.
