commit 040b8907ccf1c78d020aca29800036565d761d73 upstream.
With the new static annotation, the compiler warns when the functions are actually unused:
drivers/gpu/drm/rockchip/cdn-dp-core.c:1123:12: error: 'cdn_dp_resume' defined but not used [-Werror=unused-function] 1123 | static int cdn_dp_resume(struct device *dev) | ^~~~~~~~~~~~~
Mark them __maybe_unused to suppress that warning as well.
[ Not so 'new' static annotations any more, and I removed the part of the patch that added __maybe_unused to cdn_dp_suspend(), because it's used by the shutdown/remove code.
So only the resume function ends up possibly unused if CONFIG_PM isn't set - Linus ]
