[ARM] 3965/1: ixp2000: fix handling of pci master aborts
The master abort check in ixp2000_pci_read_config() recently started failing due to the compiler optimising out the read access following the clearing of pci_master_aborts. Mark pci_master_aborts volatile to force the compiler to reload it on every use. Signed-off-by: Lennert Buytenhek <buytenh@wantstofly.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
