Subject: [PATCH v3 3/9] usb: gadget: f_midi: remove alignment code for OUT endpoint
Date: Fri, 5 Aug 2016 19:34:55 +0100 [thread overview]
Message-ID: <20160805183501.11993-4-eu@felipetonello.com> (raw)
In-Reply-To: <20160805183501.11993-1-eu@felipetonello.com>
The new version of alloc_ep_req() already aligns the buffer size to
wMaxPacketSize on OUT endpoints.
