From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The variable retval is being initialized with a value that is never read
and it is being updated later with a new value. Clean this up by
initializing retval to -ENOMEM and remove the assignment to retval
on the !dev failure path.
Kudos to Rafael for the improved fix suggestion.
