From 24b390aad2930b889b6e15fc7cf7bfa7c99fad21 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 27 Jul 2015 17:09:40 -0500 Subject: [PATCH] PCI: Remove unused "pci_probe" flags The following flags are only used on x86, but they got copied to FR-V, MN10300, and SuperH: PCI_PROBE_BIOS PCI_PROBE_CONF1 PCI_PROBE_CONF2 PCI_ASSIGN_ROMS PCI_NO_CHECKS PCI_BIOS_IRQ_SCAN PCI_ASSIGN_ALL_BUSSES FR-V and MN10300 do test for PCI_ASSIGN_ROMS, but they never set it, so it's dead code. Remove the unused flags above.
