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.
