From 6d33f7bb8c3863e54f8bdede0a2bf97a3585ac20 Mon Sep 17 00:00:00 2001 From: Thomas Pugliese Date: Thu, 15 Aug 2013 12:21:30 -0500 Subject: USB: WUSBCORE: clear RPIPE stall for control endpoints When the HWA encounters a STALL on a control endpoint, it should clear the RPIPE_STALL feature on the RPIPE before processing the next transfer request. Otherwise, all transfer requests on that endpoint after the first STALL will fail because the RPIPE is still in the halted state. This also removes the unneccessary call to spin_lock_irqsave for a nested lock that was present in the first patch.
