Subject: [PATCH 8/9] can: gs_usb: gs_usb_probe(): use descriptors of current altsetting
Date: Thu,  2 Jan 2020 17:09:33 +0100	[thread overview]
Message-ID: <20200102160934.1524-9-mkl@pengutronix.de> (raw)
In-Reply-To: <20200102160934.1524-1-mkl@pengutronix.de>

From: Johan Hovold <johan@kernel.org>

Make sure to always use the descriptors of the current alternate setting
to avoid future issues when accessing fields that may differ between
settings.

Fixes: d08e973a77d1 ("can: gs_usb: Added support for the GS_USB CAN devices")
