Subject: [PATCH] drm/amd/display/dc/dce112/dce112_resource: Drop redundant null-pointer check in bw_calcs_data_update_from_pplib()
Date: Sat, 7 Aug 2021 06:35:06 -0700 [thread overview]
Message-ID: <20210807133506.243629-1-islituo@gmail.com> (raw)
The variable dc->bw_vbios is guaranteed to be not NULL by its callers.
Thus the null-pointer check can be dropped.
