[PATCH] liquidio: Use pcie_flr() instead of reimplementing it

From: Denis Efremov
Date: Thu Aug 08 2019 - 00:58:06 EST


octeon_mbox_process_cmd() directly writes the PCI_EXP_DEVCTL_BCR_FLR
bit, which bypasses timing requirements imposed by the PCIe spec.
This patch fixes the function to use the pcie_flr() interface instead.
