Subject: [PATCH 12/18] raw: use explicit llseek file operations
Date: Wed,  7 Jul 2010 23:40:14 +0200

The raw_fops may need to seek, so there should
be an explicit reference to default_llseek.
raw_ctl_fops does not contain a read or write
method, so we use noop_llseek to ignore seeking
requests without an error.
