From fcc32a21655e26d30c746b4828b33a5fd4ccfb11 Mon Sep 17 00:00:00 2001 From: Denis Efremov Date: Thu, 8 Aug 2019 07:57:53 +0300 Subject: [PATCH] liquidio: Use pcie_flr() instead of reimplementing it 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. Signed-off-by: Denis Efremov Reviewed-by: Andrew Murray Reviewed-by: Bjorn Helgaas Signed-off-by: David S.
