Subject: [PATCH] perf/x86/amd/uncore: fix error codes in amd_uncore_init()
Message-ID: <cec62eba-c4b8-4cb7-9671-58894dd4b974@moroto.mountain>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

Some of the error paths in this function return don't initialize the
error code.  Return -ENODEV.

Fixes: d6389d3ccc13 ("perf/x86/amd/uncore: Refactor uncore management")
