[PATCH v2 09/25] usb: gadget: f_tcm: Use extra number of commands

From: Thinh Nguyen
Date: Mon Jul 18 2022 - 22:07:07 EST


To properly respond to host sending more commands than the number of
streams the device advertises, the device needs to be able to reject the
command with a response. Allocate an extra request to handle 1 more
command than the number of streams.
