Subject: [PATCH 4/4] USB: gadget: f_midi: setup SuperSpeed Plus descriptors
Date: Thu, 26 Nov 2020 19:09:37 +0100	[thread overview]
Message-ID: <20201126180937.255892-4-gregkh@linuxfoundation.org> (raw)
In-Reply-To: <20201126180937.255892-1-gregkh@linuxfoundation.org>

From: Will McVicker <willmcvicker@google.com>

Needed for SuperSpeed Plus support for f_midi.  This allows the
gadget to work properly without crashing at SuperSpeed rates.
