Subject: Use bit-wise not instead of logical not.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fda5078324e0a940a2ddfdd1c63ffceb47c5a717;p=mesa.git

Use bit-wise not instead of logical not.

The assertion is checking that the low-order bits of offset are not
set.  It does this by anding the inverted offset mask with the
offset.  This is clearly intended to be a bit-wise "invert".

Fixes bug #25984.
