Subject: [PATCH 3.16 066/133] USB: serial: option: add support for D-Link
 DWM-157 C1

3.16.51-rc1 review patch.  If anyone has any objections, please let me know.

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

From: "Maciej S. Szmigiero" <mail@...iej.szmigiero.name>

commit 169e86546f5712179709de23cd64bbb15f199fab upstream.

This commit adds support (an ID, really) for D-Link DWM-157 hardware
version C1 USB modem to option driver.

According to manufacturer-provided Windows INF file the device has four
serial ports:
"D-Link HSPA+DataCard Diagnostics Interface" (interface 2; modem port),
"D-Link HSPA+DataCard NMEA Device" (interface 3),
"D-Link HSPA+DataCard Speech Port" (interface 4),
"D-Link HSPA+DataCard Debug Port" (interface 5).
