From: Maximilian Luz <luzmaximilian@gmail.com> stable inclusion from stable-v5.10.109 commit 0b2ffba2de5046e508616f3b30f0e424436d16f7 bugzilla: https://gitee.com/openeuler/kernel/issues/I574AE Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 7dacee0b9efc8bd061f097b1a8d4daa6591af0c6 upstream. For some reason, the Microsoft Surface Go 3 uses the standard ACPI interface for battery information, but does not use the standard PNP0C0A HID. Instead it uses MSHW0146 as identifier. Add that ID to the driver as this seems to work well. Additionally, the power state is not updated immediately after the AC has been (un-)plugged, so add the respective quirk for that.
