Subject: [PATCH] media: usb: siano: Fix false-positive "uninitialized variable" warning
Date: Tue, 21 May 2019 11:38:07 -0400 (EDT)	[thread overview]
Message-ID: <Pine.LNX.4.44L0.1905211136260.1634-100000@iolanthe.rowland.org> (raw)
In-Reply-To: <20190521140805.GA24615@kroah.com>

GCC complains about an apparently uninitialized variable recently
added to smsusb_init_device().  It's a false positive, but to silence
the warning this patch adds a trivial initialization.
