Masood Mehmood fd54889b65 staging: dgap: Fixed sparse error: same symbol redeclared with different type
sparse reported dgap_do_fep_load is redeclared with different type. while
fixing, I noticed __user attribute is used incorrectly in declaration.
There is no need to define __user for firware->data.

Replaced the __user with 'const uchar *' from function dgap_do_fep_load and
did the same for function dgap_do_bios_load

Alexey Khoroshilov af07daa0af staging: dgap: remove unneeded status variables
dgap_driver_start and dgap_Major_Control_Registered are used
to keep status of initialization of the driver as a whole and its "Major Control".
But the code that checks them is executed once on module init/unload.
That makes no sense in these variables as far as their values are predictable
at any time.

Also "dgap_downld" device was removed, while
device_destroy(MKDEV(DIGI_DGAP_MAJOR, 1)) is still in dgap_cleanup_module().
The patch removes it by the way.

Mark Hounschell 434b679bdb staging: dgap: Remove printks associated with sysfile creation
This patch removes printks associated with sysfile creation
and changes the dgap_create_driver_sysfiles function to return
an int so we can check for errors in the sysfile creation
process.

The printk's were flagged by checkpatch but then
driver_create_file was flagged by checkpatch for
not checking its return. So we remove the printk's
and check the return of driver_create_file.
