From 5aa182a26ca6b2427473d9c61e369c860fca628c Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Sat, 28 May 2016 18:28:51 -0500 Subject: [PATCH] PCI: generic: Simplify host bridge window iteration The switch is the only statement in the resource_list_for_each_entry() loop, so remove unnecessary "continue" statements in the switch. Remove unnecessary "goto" statements and label. Simplify checking for the required non-prefetchable memory aperture. No functional change intended.
