Revision d62668e1dd830a81ef73ec73386b420cb2a9ca62 authored by Sergei Shtylyov on 11 November 2009, 22:26:50 UTC, committed by Linus Torvalds on 12 November 2009, 15:26:00 UTC
In case of failure, device_create() returns not NULL but the error code. The current code checks for non-NULL though which causes kernel oops in sysfs_create_group() when device_create() fails. Check for error using IS_ERR() and propagate the error value using PTR_ERR() instead of fixed -ENODEV code returned now...
