Revision 1530f6f5f5806b2abbf2a9276c0db313ae9a0e09 authored by Qi Zhou on 04 January 2020, 11:02:01 UTC, committed by Greg Kroah-Hartman on 08 January 2020, 16:44:11 UTC
According to bd0e6c9614b9 ("usb: hub: try old enumeration scheme first
for high speed devices") the kernel will try the old enumeration scheme
first for high speed devices. This can happen when a high speed device
is plugged in.
But due to missing parentheses in the USE_NEW_SCHEME define, this logic
can get messed up and the incorrect result happens.
