Date: Mon, 10 Feb 2020 04:32:09 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Oliver Neukum <oneukum@...e.com>, Johan Hovold <johan@...nel.org>, Sean Young <sean@...s.org>, Mauro Carvalho Chehab <mchehab+huawei@...nel.org> Subject: [PATCH 5.5 216/367] media: iguanair: fix endpoint sanity check From: Johan Hovold <johan@...nel.org> commit 1b257870a78b0a9ce98fdfb052c58542022ffb5b upstream. Make sure to use the current alternate setting, which need not be the first one by index, when verifying the endpoint descriptors and initialising the URBs. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.
