Subject: drm/amd/display: Remove unused NUM_ELEMENTS macros
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a097dd7059cb1d4efb436092196885e3abd56518;p=thirdparty%2Fkernel%2Flinux.git

drm/amd/display: Remove unused NUM_ELEMENTS macros

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.
