[PATCH 2/2] PCI: Remove the obsolete no_pci_devices() check

From: Feng Tang
Date: Thu Aug 23 2012 - 02:55:48 EST


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 absolete. So remove it.
