-Subject: [PATCH] PCI: aardvark: Don't rely on jiffies while holding spinlock
-
-advk_pcie_wait_pio() can be called while holding a spinlock (from
-pci_bus_read_config_dword()), then depends on jiffies in order to
-timeout while polling on PIO state registers. In the case the PIO
-transaction failed, the timeout will never happen and will also cause
-the cpu to stall.
-
-This decrements a variable and wait instead of using jiffies.
