Subject: [PATCH v2 3/8] drm/msm/a6xx: fix incorrectly set uavflagprd_inv field for A650
Date:   Thu, 13 May 2021 13:13:58 -0400
Message-Id: <20210513171431.18632-4-jonathan@marek.ca>

Precedence: bulk

Value was shifted in the wrong direction, resulting in the field always
being zero, which is incorrect for A650.
