Subject: radv: fix samples_identical return value.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=67c91ef2a228b0843bdbb4b7b7128ef45e3dd71f;p=mesa.git

radv: fix samples_identical return value.

This was returning an inversion, so not doing as it should have.

We need to compare the fmask value with 0, and return the result
from that.
