From 0ad7b5c548ecf409a1fdd835bde52a8cf5371b7a Mon Sep 17 00:00:00 2001 From: Egbert Eich Date: Mon, 4 Jul 2011 07:38:33 +0200 Subject: [PATCH] PCI: set correct mask value when matching for bridges. The mask must not be zero otherwise the matching condition will never be true: ((val & mask) == set).
