cdn_dp_resume is only used under PM_SLEEP, and now that it's static an unused function warning is triggered undner !PM_SLEEP. This marks the function as possibly unused, to avoid triggering compiler warnings.

Fixes: 7c49abb4c2f8 ("drm/rockchip: cdn-dp-core: Make cdn_dp_core_suspend/resume static") Reviewed-by: Geert Uytterhoeven geert+renesas@glider.be Signed-off-by: Palmer Dabbelt palmerdabbelt@google.com --- This is breaking my builds and looks like it'll land after -rc1, so I've put it on a shared tag for-rockchip-cdn_dp_resume-v2 which will let me pull it in to my fixes. LMK if you guys want me to send this up on my own, but I'm assuming that the drm/rockchip folks will handle it. --- drivers/gpu/drm/rockchip/cdn-dp-core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
