Subject: i965/gen6_depth_state.c: Remove (gen != 6) code paths
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=11663050eb5c93ad86a120b6c3bc978142d414a4;p=mesa.git

i965/gen6_depth_state.c: Remove (gen != 6) code paths

Since this code was branched from brw_misc_state.c, it had support for
gen != 6. We can now remove this.
