Subject: [PATCH 2/2] drm/amd/display: Remove unused NUM_ELEMENTS macros
Date: Fri,  3 Apr 2026 10:22:07 +0200	[thread overview]
Message-ID: <20260403082207.1533450-3-linus.probert@gmail.com> (raw)
In-Reply-To: <20260403082207.1533450-1-linus.probert@gmail.com>

Removes unused NUM_ELEMENTS macros. Discovered while removing cases
where ARRAY_SIZE from the header <linus/array_size.h> can be used.
This also aligns with the array_size.cocci coccinelle check.

Suggested-by: Robert P. J. Day <rpjday@crashcourse.ca>
