From 3883539140b8ce67ad000938c3cd3b3e59498520 Mon Sep 17 00:00:00 2001 From: Saravana Kannan Date: Wed, 20 Nov 2019 00:02:29 -0800 Subject: [PATCH] of: property: Fix the semantics of of_is_ancestor_of() The of_is_ancestor_of() function was renamed from of_link_is_valid() based on review feedback. The rename meant the semantics of the function had to be inverted, but this was missed in the earlier patch. So, fix the semantics of of_is_ancestor_of() and invert the conditional expressions where it is used.
