From: Dexuan Cui <[email protected]>
I didn't really hit a bug, but just happened to notice the redundant line.

PATCH 2/4 Drivers: hv: vmbus: do not mark HV_PCIE as perf_device
From: Dexuan Cui <[email protected]>
The pci-hyperv driver's channel callback hv_pci_onchannelcallback() is not really a hot path, so we don't need to mark it as a perf_device, meaning with this patch all HV_PCIE channels' target_cpu will be CPU0.
