This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit 5377adb092664d336ac212499961cac5e8728794 upstream.
usb_parse_ss_endpoint_companion() now decodes the burst multiplier
correctly in order to check that it's <= 3, but still uses the wrong
expression if warning that it's > 3.
Fixes: ff30cbc8da42 ("usb: Use the USB_SS_MULT() macro to get the ...")
