Subject: [PATCH] drm/amd/display: use ARRAY_SIZE for base60_refresh_rates
Date: Wed, 9 Jun 2021 18:09:26 +0800 [thread overview]
Message-ID: <1623233366-100202-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)
Use ARRAY_SIZE instead of dividing sizeof array with sizeof an
element.
Clean up the following coccicheck warning:
./drivers/gpu/drm/amd/display/dc/core/dc_resource.c:448:47-48: WARNING:
Use ARRAY_SIZE.
