Check for attribute_group structures that are only passed as a second
argument to the functions sysfs_remove_group and sysfs_create_group. As
these arguments are constant so, attribute_group structures having this
property can also be made constant.

Remove FSF address because it's known in the past that it has changed.
Also, remove the pointless "do not change the coding style" comments
because it's one of the reasons why it's in staging and it's quite
contradictory to what it says in TODO. Also, they contain wrong e-mails
of people which are responsible for these drivers - see TODO or
MAINTAINERS for that. We can preserve the original copyright at the top
of the most files because it shows who originally made them.

The polling counter variable is only exposed via sysfs and has no other
purpose.
Now, since the polling shall be implemented as a board specific feature
rather than being global in the driver this counter is obsolete.

This commit removes the driver's global state variable. This is ok
because the state was changed only once at the end of init phase thus
the future usage of this variable is pointless.

Casting the return value which is a void pointer is redundant.
The conversion from void pointer to any other pointer type is
guaranteed by the C programming language.

This patch removes the dgnc_proc.c and dgnc_proc.h files and all
references to proc functions in dgnc_driver.c. This also removes proc.h
from the include headers in driver.c, mgmt.c and sysfs.c and proc.o
from the Makefile.
Drivers now use sysfs instead of proc.

This patch adds the DGNC driver. This is a TTY Serial Port
Driver for the Digi International Neo and Classic PCI based product
line by Digi International <http://www.digi.com>.
This driver isn't hooked up to the build system because it doesn't
build, it merely adds the driver written by Digi to the kernel tree so
that it can be cleaned up and fixed up properly over time.
