Subject: [PATCH AUTOSEL 4.14 10/16] perf/arm_pmu_platform: Fix error handling

From: Robin Murphy <robin.murphy@....com>

[ 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.
