Subject: [PATCH AUTOSEL 4.18 18/45] drm/amdgpu/powerplay: fix missing break in switch statements
From: Colin Ian King <colin.king@...onical.com>
[ Upstream commit 14b284832e7dea6f54f0adfd7bed105548b94e57 ]
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.")
