From 2542787430fc46b4e07e0da4c6ec80ed230032e5 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Thu, 16 Jun 2011 20:36:55 +0200 Subject: [PATCH] usb: gadget: dummy_hcd: use dummy_pullup() instead of open coding The removed code does the same thing as dummy_pullup(). The only difference is that in dummy_udc_stop() the first dummy_pullup() did not call usb_hcd_poll_rh_status().
