Subject: [PATCH] patch: usb3-xhci
Squashed commit of the following:
commit 73cb422f860a84aca7a19114936ead1794d77890
Author: m. allan noah <kitno455@gmail.com>
Date: Tue Dec 16 10:23:55 2014 -0500
sanei_usb: Linux USB3/xhci workarounds
add calls to sanei_usb_set_altinterface in sanei_usb_close and
sanei_usb_clear_halt- hopefully work around USB3/xhci problems
in Linux. Also, remove some unused code, and fix debug messages.
(cherry picked from commit 014b45d920f1fb630e1a31bb01f1da02ea2a6a87)
