From ec42899c2f9cf35e25e93c61ab9948e488de1825 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 20 Apr 2012 09:33:31 +0300 Subject: [PATCH] USB: wwan: remove an unneeded check We already verified that "status" was zero on this else branch. Since zero is not equal to -ESHUTDOWN, this condition is always true. I removed it and pull everything in an indent level. This doesn't change how the code works, it's just a cleanup.
