From 794ba09bf30054c81832e61b49a64a56c95c5a9f Mon Sep 17 00:00:00 2001 From: Tomasz Nowicki Date: Thu, 21 Nov 2013 12:19:55 +0800 Subject: ACPICA: Delete all attached data objects during namespace node deletion. This fix updates namespace node deletion to delete the entire list of attached objects (attached via acpi_attach_data) instead of just one of the attached items. ACPICA BZ 1024.
