Subject: i965/vec4: Use the correct offset for the swizzle shift in push constants
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b3f43822c72301c904fd2824ae3edcd20ea93a29;p=mesa.git

i965/vec4: Use the correct offset for the swizzle shift in push constants

This was actually caught by Ken in review the first time around but somehow
didn't get fixed before the patches were pushed. :-(
