From 4bd8b4de6f806f1429d23a2f6e2549ed0e8bc49b Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 30 Nov 2011 11:43:41 +0300 Subject: [PATCH] Staging: line6: NULL dereference in dev_err() "line6" hasn't been set at this point and we should be using &interface->dev instead. Gcc would have complained about this if it weren't for the fact that we initialized line6 to NULL. I removed the initialization.
