Subject: [PATCH v5 3/5] usb: gadget: udc-core: remove unused usb_udc_attach_driver()
Date: Tue, 23 Jun 2015 01:01:12 +0300	[thread overview]
Message-ID: <1435010474-13419-4-git-send-email-ruslan.bilovol@gmail.com> (raw)
In-Reply-To: <1435010474-13419-1-git-send-email-ruslan.bilovol@gmail.com>

Now when last user of usb_udc_attach_driver() is switched
to passing UDC name via usb_gadget_driver struct, it's safe
to remove this function
