drm/amd/powerplay: Fix missing break in switch

2019-02-15T07:11:06+00:00

commit 2f10d823739680d2477ce34437e8a08a53117f40 upstream. 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.
