wait_time_microsec = max(wait_time_microsec, (uint32_t) DPIA_CLK_SYNC_DELAY); Above line is trying to assign the maximum value between 'wait_time_microsec' and 'DPIA_CLK_SYNC_DELAY' to wait_time_microsec. However, 'wait_time_microsec' has not been assigned a value before this line, initialize 'wait_time_microsec' at the point of declaration. Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_training_dpia.c:697 dpia_training_eq_non_transparent() error: uninitialized symbol 'wait_time_microsec'.
