Subject: Re: [PATCH] perf/x86/amd/uncore: fix error codes in amd_uncore_init()

The surprising thing is the Clang doesn't detect the bug either.  It's
strange.  (I found this bug with Smatch).

Also I notice that my Fixes tag wasn't correct either.  That patch did
have a missing error code bug, but "ret" was set to zero.  :/
