From f8cffc84a2ff8efc2ecca6128485877109e499f5 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sat, 28 Sep 2013 00:05:34 -0300 Subject: [PATCH] usb: gadget: udc-core: Do not report -EISNAM error from gadgetfs When mounting a gadgetfs the following error message is seen: $ modprobe gadgetfs gadgetfs: USB Gadget filesystem, version 24 Aug 2004 $ mkdir /dev/gadget $ mount -t gadgetfs none /dev/gadget nop ci_hdrc.0: failed to start (null): -120 The error comes from gadgetfs_probe(), which returns -EISNAM (-120). As Alan Stern explains[1], this is the normal behavior: "It is a temporary measure, used only when the file system is set up initially. The real bind routine is gadgetfs_bind(), which gets called when userspace configures the gadget. In short, this is how it is intended to work. It isn't a bug." [1] http://marc.info/?l=linux-usb&m=138029668707075&w=2 So in order to prevent the error message, do not report EISNAM as an error.
