This patch merges two lines in a single line if immediate

The dgnc_Major_Control_Registered variable purpose was to act as a flag
to indicate if the character device has been successfully registered
into the kernel. This flag was later checked in the module cleanup
function to know if the character device needs to be deregistered.
However the {device,class}_destroy and unregister_chrdev functions may
be called with 'invalid' data perfectly fine. This means that this
variable is not needed and can safely be removed which is what this
commit does.

The polling counter variable is only exposed via sysfs and has no other

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rather than being global in the driver this counter is obsolete.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 fixes the following checkpatch warnings:
WARNING: externs should be avoided in .c files

+int dgnc_init_module(void);
#81: FILE: drivers/staging/dgnc/dgnc_driver.c:81:
+void dgnc_cleanup_module(void);
This was caused by putting the declarations for module init and module
exit fucntions on the top of the file. The fix removes these
declarations plus it also corrects the type of the init/exit functions.
Due to the dependency between init and exit functions the
dgnc_cleanup_module had to be put first.
