[PATCH 06/12] gigaset: fix device ERROR response handling (v2)

Tilman Schmidt
2009-09-18T23:58:50Z

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"

Impact: error handling bugfix
