From 1067e2496e936d55b24639fc583713ae05e71f61 Mon Sep 17 00:00:00 2001 From: Zhang Xiaoxu Date: Mon, 16 Nov 2020 15:18:01 +0100 Subject: [PATCH] media: tvp5150: Fix wrong return value of tvp5150_parse_dt() [ Upstream commit eb08c48132a1f594478ab9fa2b6ee646c3513a49 ] If of_graph_get_endpoint_by_regs() return NULL, it will return 0 rather than an errno, because we doesn't initialize the return value.
