Subject: [20/27] media: ttusb-budget: use usb_fill_int_urb()
Date: Wed, 20 Jun 2018 13:00:58 +0200 [thread overview]
Message-ID: <20180620110105.19955-21-bigeasy@linutronix.de> (raw)
Using usb_fill_int_urb() helps to find code which initializes an URB. A
grep for members of the struct (like ->complete) reveal lots of other
things, too.
