ACPI: add missing win8 OSI comment to blacklist

felipec · rafaeljw · commit 068aab7766cf · 2013-10-10T02:25:02.000+02:00
In my original patch[1] I wrote a comment describing the reason for disabling Windows 2012 OSI mode for a group of machines, however, due to unknown reasons (probably a conflict resolution mismatch), the comment was dropped in 94fb982 (ACPI: blacklist win8 OSI for buggy laptops). Since Matthew Garrett is making a big deal out of the lack of comments in a separate patch[2], it might make sense to re-introduce the missing comment so that other patch is not blocked and users don't suffer.
