I am not a fan of assigning pointers to struct members to local 
variables unless they're shortening lines to fit on one row instead of 
using two. Whenever we add such a variable we hide information. After 
that being said - in this particular case the device 'dev' points to is 
quite obvious so I am not completely against the change if other see the 
value.

I like this. Thanks.
