Subject: USB: ti_usb_3410_5052: fix big-endian firmware handling
From: Johan Hovold <jhovold@xxxxxxxxx>
commit e877dd2f2581628b7119df707d4cf03d940cff49 upstream.
Fix endianess bugs in firmware handling introduced by commits cb7a7c6a
("ti_usb_3410_5052: add Multi-Tech modem support") and 05a3d905
("ti_usb_3410_5052: support alternate firmware") which made the driver
use the wrong firmware for certain devices on big-endian machines.
