Subject: ACPI: fix inconsistent acpi event format From: Yi Yang <yi.y.yang@intel.com>
Event format acpi generates for /proc/acpi/event is different from that for generic netlink interface. Here are i got:
>From /proc/acpi/event, i got the following events when i suspend and resume Acer's Aspire One:
battery BAT1 00000080 00000000 battery BAT1 00000081 00000000 ac_adapter ACAD 00000080 00000001 battery BAT1 00000080 00000000
But from generic netlink socket, i got the following events when i suspend and resume Acer's Aspire One:
battery PNP0C0A:00 00000080 00000000 battery PNP0C0A:00 00000081 00000000 ac_adapter ACPI0003:00 00000080 00000001 battery PNP0C0A:00 00000080 00000000
Such inconsistent event format will make acpid or hald confused, this patch fixes this issue, it makes acpid or hald see the same thing no matter they use /proc/acpi/event or generic netlink interface.
After applying this patch, event format i got from /proc/acpi/event and generic netlink interface is same, all of them are:
battery BAT1 00000080 00000000 battery BAT1 00000081 00000000 ac_adapter ACAD 00000080 00000001 battery BAT1 00000080 00000000
Please consider applying, thanks.
