Subject[PATCH 3.16 149/245] can: gs_usb: gs_usb_probe(): use descriptors of current altsetting
3.16.83-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Johan Hovold <johan@kernel.org>

commit 2f361cd9474ab2c4ab9ac8db20faf81e66c6279b upstream.

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