From 9c15c5738b5219fdc273e8923b2c1a9d5e8ce3b3 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sat, 13 Sep 2014 12:26:37 +0200 Subject: uas: zap_pending: data urbs should have completed at this time The data urbs are all killed before calling zap_pending, and their completion handler should have cleared their inflight flag. Do not 0 the data inflight flags, and add a check for try_complete succeeding, as it should always succeed when called from zap_pending.
