Subject: [PATCH] x86/perf/intel/rapl: Fix module name collision with powercap
intel-rapl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since commit 4b6e2571bf00 the rapl perf module calls itself intel-rapl. That
name was already in use by the rapl powercap driver, which now fails to load
if the perf module is loaded. Fix the problem by renaming the perf module to
intel-rapl-perf, so that both modules can coexist.
Fixes: 4b6e2571bf00 ("x86/perf/intel/rapl: Make the Intel RAPL PMU driver modular")
