From 1bf24e95f6b11b1b4bcf622ab92de43fe66aa310 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 7 Aug 2018 13:19:35 +0100 Subject: [PATCH] nvmem: core: return error code instead of NULL from nvmem_device_get [ Upstream commit ca6ac25cecf0e740d7cc8e03e0ebbf8acbeca3df ] nvmem_device_get() should return ERR_PTR() on error or valid pointer on success, but one of the code path seems to return NULL, so fix it.
