Subject: nv50: fix bogus parameters when processing sample instructions
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2947f00bc466a03e3cc99fcf6c6334c2a896bfbe;p=mesa.git

nv50: fix bogus parameters when processing sample instructions

Discovered accidentally when changing SAMPLE_L definition.
Turns out the lod arguments were already correct for the new definition
but the compare and derivs were not.
