From 3f399b5d7189bcb608c75abc85fe39f7a5509cfa Mon Sep 17 00:00:00 2001 From: Armin Wolf Date: Sun, 21 Jan 2024 21:08:24 +0100 Subject: platform/x86: wmi: Use ACPI device name in netlink event MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The device name inside the ACPI netlink event is limited to 15 characters, so the WMI device name will get truncated. This can be observed with kacpimon when receiving an event from WMI device "9DBB5994-A997-11DA-B012-B622A1EF5492": netlink: 9DBB5994-A997- 000000d0 00000000 Fix this by using the shorter device name from the ACPI bus device instead. This still allows users to uniquely identify the WMI device by using the notify id (0xd0).
