Subject: ac/nir: remove misleading condition
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=29f46488cc41d11f44e5e7a59bcedae761707d76;p=mesa.git

ac/nir: remove misleading condition

location is never set to INTERP_SAMPLE, and Nicolai comments:
"... that part is misleading. location refers to the base location, not
the final location of the sample, and it can never be INTERP_SAMPLE."
