Subject: [PATCH v4 5/7] usb: gadget: f_midi: set altsettings only for MIDIStreaming interface
Date: Mon, 26 Oct 2015 16:55:07 +0000 [thread overview]
Message-ID: <1445878509-12084-6-git-send-email-eu@felipetonello.com> (raw)
In-Reply-To: <1445878509-12084-1-git-send-email-eu@felipetonello.com>
This avoids duplication of USB requests for OUT endpoint and
re-enabling endpoints.
