From e877dd2f2581628b7119df707d4cf03d940cff49 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Sun, 11 Aug 2013 16:49:23 +0200 Subject: [PATCH] USB: ti_usb_3410_5052: fix big-endian firmware handling 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.
