If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 46d73b32b068ce6b85ceb8b58672b792209f0a71 Author: Pali Rohár <pali@xxxxxxxxxx> Date: Thu Nov 25 17:01:47 2021 +0100 PCI: aardvark: Fix checking for MEM resource type [ Upstream commit 2070b2ddea89f5b604fac3d27ade5cb6d19a5706 ] IORESOURCE_MEM_64 is not a resource type but a type flag. Remove incorrect check for type IORESOURCE_MEM_64.
