Subject: [PATCH][next] drm/amdgpu: Fix masking binary not operator on two mask operations
Date: Fri, 22 Jan 2021 15:00:22 +0000	[thread overview]
Message-ID: <20210122150022.209454-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

Currently the ! operator is incorrectly being used to flip bits on
mask values. Fix this by using the bit-wise ~ operator instead.

Addresses-Coverity: ("Logical vs. bitwise operator")
Fixes: 3c9a7b7d6e75 ("drm/amdgpu: update mmhub mgcg&ls for mmhub_v2_3")
