Get rid of it by adding a function prototype
'optc3_wait_drr_doublebuffer_pending_clear(struct timing_generator *optc)' on
drivers/gpu/drm/amd/display/dc/dcn30/dcn30_optc.h

I would prefer if you marked the function as static instead, since it is
only used in dcn30_optc.c.

void optc3_set_drr_trigger_window(struct timing_generator *optc,
