Subject: gbm: Fix the alpha masks in the GBM format table.
X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=880573e7370b866c94513f59ad0bb0b10660643f;hp=b54bf0e3e3378725dec924f8152dcb012dffcd2e

gbm: Fix the alpha masks in the GBM format table.

Once GBM started looking at the values of the alpha masks, ARGB/ABGR
wouldn't match any more because we had both A and R in the low bits.
