Subject: [PATCH 0/2] drm/amd/display: Replace NUM_ELEMENTS -> ARRAY_SIZE
Date: Fri,  3 Apr 2026 10:22:05 +0200	[thread overview]
Message-ID: <20260403082207.1533450-1-linus.probert@gmail.com> (raw)

There's a coccinelle script which attempts to replace cases where sizeof
array is divided by sizeof an element. Most of these occurences have
been handled but a few remained in this driver in the shape of the
NUM_ELEMENTS macro.

In two cases the NUM_ELEMENTS macro has been removed and its use has
been replaced by ARRAY_SIZE. (1)
In 4 files the NUM_ELEMENTS macro existed but was never used so it has
just been removed. (2)

I couldn't trace why these cases hadn't been picked up by the coccinelle
check. Just NAK this if there's a reason for NUM_ELEMENTS to be kept as
is. Thanks.
