Subject: [PATCH] drm/amd/display: use ARRAY_SIZE for base60_refresh_rates
Date:   Wed,  9 Jun 2021 18:09:26 +0800
Message-Id: <1623233366-100202-1-git-send-email-jiapeng.chong@linux.alibaba.com>
Precedence: bulk

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.
