Subject: ac/nir: Fix compiler warning about uninitialized dw_addr.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=091bff831721b62243840038f505af0abd9436c1;p=mesa.git

ac/nir: Fix compiler warning about uninitialized dw_addr.

Even switching the def's condition to be the same chip revision check as
the use, the compiler doesn't figure it out.  Just NULL-init it.

Fixes: ec53e527421d ("ac/nir: Add ES output to LDS for GFX9.")
