ACPI processor: Remove unneeded variable passed by acpi_processor_hot…

…add_init V2 V2: Fix typo: pr->handle -> pr, here: acpi_processor_hotadd_init(pr) This is a very small part taken from patches which afaik are coming from Yunhong Jiang (for a Xen not a Linus repo?). Cleanup only: no functional change. Advantage (beside cleanup) is that other data of the pr (acpi_processor) struct in the acpi_processor_hotadd_init() is needed later, for example a newly introduced flag: pr->flags.need_hotplug_init Signed-off-by: Thomas Renninger <[email protected]> CC: Bjorn Helgaas <[email protected]> CC: Jiang, Yunhong <[email protected]> Signed-off-by: Len Brown <[email protected]>
