X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7817e265233e4b216aad509fc003cf4face238b9;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ACPICA: Fix a regression for deletion of Alias() objects. Fixes a regression introduced by commit e23d9b829754 (ACPICA: Namespace: Properly null terminate objects detached from a namespace node) In the case of Alias namespace nodes, the node simply points to the aliased node via the Object field; thus we cannot assume that the object is an operand object.
