Subject: [PATCH v2 09/20] Staging: ipack: reset previous timeouts during device registration.

From: Jens Taprogge <jens.taprogge@...rogge.org>

Resetting the previous timeout we avoid to read the timeout status register
and see timeout errors that don't correspond to the present state of the
device.
