[PATCH AUTOSEL 5.4 17/34] perf/arm_pmu_platform: Fix error handling

From: Sasha Levin
Date: Sun May 02 2021 - 10:07:03 EST


From: Robin Murphy <robin.murphy@xxxxxxx>

[ Upstream commit e338cb6bef254821a8c095018fd27254d74bfd6a ]

If we're aborting after failing to register the PMU device,
we probably don't want to leak the IRQs that we've claimed.
