From: Armin Wolf Date: Sun, 21 Jan 2024 20:08:24 +0000 (+0100) Subject: platform/x86: wmi: Use ACPI device name in netlink event X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3f399b5d7189bcb608c75abc85fe39f7a5509cfa;p=linux.git platform/x86: wmi: Use ACPI device name in netlink event 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).
