Subject: [PATCH 10/11] ibm_newemac: Call dev_set_drvdata() before tah_reset()
Date: Wed, 05 Dec 2007 11:14:32 +1100 [thread overview]
Message-ID: <20071205001541.F2D69DE109@ozlabs.org> (raw)
From: Valentine Barshak <vbarshak@ru.mvista.com>
The patch moves dev_set_drvdata(&ofdev->dev, dev) up before tah_reset(ofdev)
is called to avoid a NULL pointer dereference, since tah_reset uses drvdata.
