Subject[PATCH 2.6.28-rc3] ACPI: fix inconsistent acpi event format (resent)
From

Subject: ACPI: fix inconsistent acpi event format
From: Yi Yang <yi.y.yang@intel.com>

Hi, Len

Please ignore last one and use this patch, this patch also fixes other acpi event format
issues in another several acpi drivers.

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.
