From 5993e79398d35d665b4c84ecb79aba3b83a965cc Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 22 Jan 2021 15:00:22 +0000 Subject: [PATCH] drm/amdgpu: Fix masking binary not operator on two mask operations Currently the ! operator is incorrectly being used to flip bits on mask values. Fix this by using the bit-wise ~ operator instead.
