[PATCH 5.15 054/262] PCI: aardvark: Fix checking for MEM resource type

From: Greg Kroah-Hartman
Date: Mon Mar 07 2022 - 04:51:13 EST


From: Pali Rohár <pali@xxxxxxxxxx>

[ Upstream commit 2070b2ddea89f5b604fac3d27ade5cb6d19a5706 ]

IORESOURCE_MEM_64 is not a resource type but a type flag.

Remove incorrect check for type IORESOURCE_MEM_64.
