[PATCH 3.12 65/91] usb: Use the USB_SS_MULT() macro to decode burst multiplier for log message

From: Jiri Slaby
Date: Tue Jan 05 2016 - 12:57:25 EST


From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me 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 ...")
