Subject: [char-misc-next] mei: pxp: match against PCI_CLASS_DISPLAY_OTHER
Date: Sun, 21 Apr 2024 12:07:01 +0300 [thread overview]
Message-ID: <20240421090701.216028-1-tomas.winkler@intel.com> (raw)
From: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com>
The ATS-M class is PCI_CLASS_DISPLAY_OTHER instead of
PCI_CLASS_DISPLAY_VGA, so we need to match against that class as well.
The matching is still restricted to Intel devices only.
Fixes: ceeedd951f8a ("mei: pxp: match without driver name")
