[PATCH]X86:PCI: Fix an uninitialized variable warning

From: wanlong . gao
Date: Mon Apr 04 2011 - 05:15:40 EST


From: Wanlong Gao <wanlong.gao@xxxxxxxxx>

If it was preempted , and the variable aer_mask_override is
changed after the spin_unlock_irqrestore , it will write an
uninitialized variable by the pci_write_config_dword() function .
