Subject: [PATCH 1/1] drivers/staging/vt6656/main_usb.c: usb_device_reset

Removed the usb_device_reset(), replace with call to usb_reset_device() 
directly. Plus it removes the confusing function name and addressed 
the checkpatch warning as well by swap string in the dev_warn() call with 
__func__ argument, instead of explicitly calling the function name in 
the string:

        WARNING: Prefer using "%s", __func__ to embedded function names
        #417: FILE: main_usb.c:417:
        +                        "usb_device_reset fail status=%d\n", status);

        total: 0 errors, 1 warnings, 1058 lines checked

And after fix:

         main_usb.c has no obvious style problems and is ready for submission.
