Subject: ACPICA: Fix for Load/LoadTable to specify load location
X-Git-Tag: v2.6.26-rc1~101^2~45
X-Git-Url: https://git.kernelconcepts.de/?a=commitdiff_plain;h=7f4ac9f91383a0707de559dc8fbca986fc2d302f;p=karo-tx-linux.git

ACPICA: Fix for Load/LoadTable to specify load location

Fixed a problem with the Load and LoadTable operators where
the table location within the namespace was ignored. Instead,
the table was always loaded into the root or current scope.
