Subject: i965: Shut up Coverity warning about HiZ buffers.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=445367242a221d8e7d0f8ce31a9df75e86f8af0e;p=mesa.git

i965: Shut up Coverity warning about HiZ buffers.

Here the AUX_USAGE_* mode indicates that we have HiZ, so we will have
a HiZ buffer.  But Coverity doesn't know that, so it thinks it might
be NULL because we checked hiz_buf != NULL earlier.
