+Subject: [PATCH 1169/2940] drm/amd/powerplay: Fix missing break in switch
+
+Add missing break statement in order to prevent the code from falling
+through to the default case.
+
+The resoning for this is that pclk_vol_table is an automatic variable.
+So, it makes no sense to update it just before falling through to the
+default case and return -EINVAL.
+
+This bug was found thanks to the ongoing efforts to enabling
+-Wimplicit-fallthrough.
+
+Fixes: cd70f3d6e3fa ("drm/amd/powerplay: PP/DAL interface changes for dynamic clock switch")
