Subject: [PATCH v3 10/10] usb: gadget: aspeed: Implement dummy hub TT requests
Date: Fri, 26 Jul 2019 15:05:39 +1000 [thread overview]
Message-ID: <20190726050539.7875-11-benh@kernel.crashing.org> (raw)
In-Reply-To: <20190726050539.7875-1-benh@kernel.crashing.org>
We just accept them instead of stalling and return
zeros on GetTTState.
