There are several switch statements that are missing break statements. Add missing breaks to handle any fall-throughs corner cases.

Detected by CoverityScan, CID#1457175 ("Missing break in switch")

Fixes: 18aafc59b106 ("drm/amd/powerplay: implement fw related smu interface for iceland.") Signed-off-by: Colin Ian King colin.king@canonical.com

Acked-by: Huang Rui ray.huang@amd.com

Applied. thanks!
