Fernando Apesteguia 9b33f918c0 staging: dgnc: Fix lines longer than 80 characters
For two cases (beginning and end of the patch) I opted to create small
functions instead of breaking the the lines in a weird way.

The other changes are simple ones: either by breaking the line when
appropriate or by turning a comment into a multi-line one.

Greg Kroah-Hartman 1eb388b67a staging: dgnc: remove sysfs files
The dgnc driver has no business creating "custom" sysfs files just for a
single tty driver.  Combined with the odd way they are created, it's
just a mess, so remove them entirely as I am tired of tripping over them
when doing driver core changes.
