From e9bf1040f649d89db3c2e060d1b0b56665a4fb93 Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Thu, 23 Aug 2012 15:45:47 +0800 Subject: [PATCH] PCI: Remove the obsolete no_pci_devices() check In function pci_get_subsys() there is a check: /* * pci_find_subsys() can be called on the ide_setup() path, * super-early in boot. But the down_read() will enable local * interrupts, which can cause some machines to crash. So here we * detect and flag that situation and bail out early. */ if (unlikely(no_pci_devices())) return NULL; But there is no ide_setup() now, and no down_read() either, which makes the check obsolete. So remove it.
