3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Oliver Neukum <oneukum@xxxxxxx>
commit 1cab4c68e339086cdaff7535848e878e8f261fca upstream.
Reported by Alif Mubarak Ahmad:
This device vendor and product id is 1c9e:9800
It is working as serial interface with generic usbserial driver.
I thought it is more suitable to use usbserial option driver, which has
better capability distinguishing between modem serial interface and
micro sd storage interface.
