Subject: [PATCH v7 04/13] PCI/ERR: Rename reset_link() to reset_subordinate_device()

From: Sean V Kelley <sean.v.kelley@...el.com>

reset_link() appears to be misnamed. The point is to really
reset any devices below a given bridge. So rename it to
reset_subordinate_devices() to make it clear that we are
passing a bridge with the intent to reset the devices below it.
