From ed6456afef0da57edfd87ce9142813d08a571137 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 14 Jun 2017 12:10:56 +0300 Subject: [PATCH] Staging: rtl8723bs: fix an error code in isFileReadable() The caller only cares about zero vs non-zero so this code actually works fine but we should be returning a negative error code instead of a valid pointer casted to int.
