Shang XiaoJing b131304fe7 perf/smmuv3: Fix hotplug callback leak in arm_smmu_pmu_init()
[ Upstream commit 6f2d566b46 ]

arm_smmu_pmu_init() won't remove the callback added by
cpuhp_setup_state_multi() when platform_driver_register() failed. Remove
the callback by cpuhp_remove_multi_state() in fail path.

Similar to the handling of arm_ccn_init() in commit 26242b3300 ("bus:
arm-ccn: Prevent hotplug callback leak")
