From 40507377261250fe19e441300788c77b748688cb Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 24 Oct 2012 18:31:09 +0200 Subject: uhci: Move emptying of the queue's asyncs' queue to uhci_queue_free Cleanup: all callers of uhci_queue_free first unconditionally cancel all remaining asyncs in the queue, so lets move this to uhci_queue_free().
