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.

From: Arnd Bergmann <arnd@arndb.de>

Three functions in the amdgpu display driver cause -Wmissing-prototype
warnings:

drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:1858:6: error: no previous prototype for 'is_timing_changed' [-Werror=missing-prototypes]
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm_mst_types.c:210:6: error: no previous prototype for 'is_synaptics_cascaded_panamera' [-Werror=missing-prototypes]
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_optc.c:294:6: error: no previous prototype for 'optc3_wait_drr_doublebuffer_pending_clear' [-Werror=missing-prototypes]

is_timing_changed() is actually meant to be a global symbol, but needs
a proper name and prototype, while the other two can just be made static.

Fixes: 54c7b715b5ef ("drm/amd/display: Add DSC Support for Synaptics Cascaded MST Hub")
Fixes: 17ce8a6907f7 ("drm/amd/display: Add dsc pre-validation in atomic check")

This has already been fixed as of commit 669f4ac40947 ("drm/amd/display:
set variable dccg314_init storage-class-specifier to static") in
amd-staging-drm-next.

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.

It seems like, only the changes for is_timing_changed() are in this patch.

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.
