From 9340e9dc9d000781a396917d3ca8e5a705cae765 Mon Sep 17 00:00:00 2001 From: Eli Billauer Date: Tue, 17 Dec 2013 21:36:29 +0200 Subject: [PATCH] staging: xillybus: Return -EIO if *_iomap fails, instead of 0 This patch replicates the correction made by Wei Yongjun on a second occurrence of the same bug. The first correction was in commit 8eec4555511bfa1f8a2e0a2de45c988fd30c3efb. Bug fixed: The error code was not set, so the error condition wasn't reflected in the return value.
