From a58204ab91ad8cae4d8474aa0ba5d1fc504860c9 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Mon, 13 Nov 2017 17:59:18 +0900 Subject: [PATCH] usb: gadget: udc: renesas_usb3: fix number of the pipes This controller on R-Car Gen3 has 6 pipes that included PIPE 0 for control actually. But, the datasheet has error in writing as it has 31 pipes. (However, the previous code defined 30 pipes wrongly...) Anyway, this patch fixes it.
