From: Arnd Bergmann <arnd@arndb.de>
The newly introduced global function is not declared in a header or
called from another file, causing a harmless warning with sparse
or W=1 builds:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn314/dcn314_dccg.c:277:6: error: no previous prototype for 'dccg314_init' [-Werror=missing-prototypes]
Mark it static instead.
Fixes: 6f6869dcf415 ("drm/amd/display: prep work for root clock optimization enablement for DCN314")

Indeed. I made this patch a few weeks ago, and it looks like the other two were fixed in the same way that I had in the meantime, so the other changes got silently dropped during a rebase. I've updated the changelog text and sent a v2 now. Arnd ^ permalink raw reply [flat|nested] 6+ messages in thread

Ok, thanks. I waited for a rebase on today's linux-next before posting mine to make sure it's not already fixed, it must have just missed the cut-off.
