From 29ddae2a40883640941932f73eb3d15535c3f4a2 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 4 Jun 2013 22:44:27 +0800 Subject: [PATCH] pch_phub: fix error return code in pch_phub_probe() Error code had been assigned to retval in some error handling case but never use it, 0 is always returned in those case, this patch fix them to return a negative error code.
