Subject: Re: [PATCH 14/52] net: cxgb4vf: remove unnecessary pci_set_drvdata()
Date: Wed, 11 Sep 2013 10:24:16 -0700 [thread overview]
Message-ID: <5230A740.4020503@chelsio.com> (raw)
In-Reply-To: <005801ceaec1$6b8d3320$42a79960$%han@samsung.com>
I agree that the redundant pci_set_drvdata(pdev, NULL) in
cxgb4vf_pci_probe() under the err_release_regions: label is unneeded,
but don't we need to NULL out the PCI Driver Data under the
err_free_adapter: label and also in cxgb4vf_pci_remove()? Or is that
handled automatically in the PCI infrastructure code which calls the
Device Probe and Remove routines? Mostly I was just being an
obsessively clean housewife assuming that we'd want to clean up these
references ...
