From 05eae94f2a2b6a05f10495c77162d0fecae67264 Mon Sep 17 00:00:00 2001 From: Tilman Schmidt Date: Tue, 6 Oct 2009 12:18:46 +0000 Subject: gigaset: fix device ERROR response handling Clear out pending command that got rejected with 'ERROR' response. This fixes the bug where unloading the driver module would hang with the message: "gigaset: not searching scheduled commands: busy" after a device communication error.
