From 8cb2268001f9553f9ff83416ce3f009c4ab1e089 Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Wed, 18 Apr 2012 09:58:23 +0200 Subject: [PATCH] isp1760-hcd: move dequeued qtds to the front in qh Make sure that dequeued urbs get handled first by collect_qtds. To achieve that we better move them up to the head in the qh list. This for instance fixes hanging serial devices, which wait for dequeued urbs to properly close their device node.
