Subject: [PATCH 3/9] ALSA: ua101: use usb_fill_int_urb()
Date: Tue, 19 Jun 2018 23:55:15 +0200 [thread overview]
Message-ID: <20180619215521.13688-4-bigeasy@linutronix.de> (raw)
In-Reply-To: <20180619215521.13688-1-bigeasy@linutronix.de>
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.
