Subject: [PATCH RFCv3 13/17] [media] dvb-bt8xx: Don't return -EFAULT when a device is not found
Date: Wed, 6 Jul 2011 15:03:59 -0300	[thread overview]
Message-ID: <20110706150359.28924e4a@pedra> (raw)
In-Reply-To: <cover.1309974026.git.mchehab@redhat.com>

When a device (or their PCI structs) are not found, the error should
be -ENODEV. -EFAULT is reserved for errors while copying arguments
from/to userspace.
