Revision 47f8bcf362410b631a4d99ff5c79ec6b9dd3ace6 authored by Matthew Garrett on 20 July 2010, 17:52:00 UTC, committed by Dave Jones on 26 July 2010, 19:25:34 UTC
The pcc specification documents an _OSC method that's incompatible with the
one defined as part of the ACPI spec. This shouldn't be a problem as both
are supposed to be guarded with a UUID. Unfortunately approximately nobody
(including HP, who wrote this spec) properly check the UUID on entry to the
_OSC call. Right now this could result in surprising behaviour if the pcc
driver performs an _OSC call on a machine that doesn't implement the pcc
specification. Check whether the PCCH method exists first in order to reduce
this probability.
