devm_iounmap is called automatically that's why remove it from the code
dev_set_drvdata(dev, NULL) is called by generic code
after device_release or on probe failure.

* [PATCH 00/21] video: remove unnecessary pci_set_drvdata()
From: Jingoo Han @ 2013-09-12 6:49 UTC (permalink / raw)
To: linux-fbdev
Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound),
the driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

* [PATCH 06/21] video: gx1fb: remove unnecessary pci_set_drvdata()
From: Jingoo Han @ 2013-09-12 6:53 UTC (permalink / raw)
To: linux-fbdev
From fbb1885952efb15a46d03aac050c38fc9179594e Mon Sep 17 00:00:00 2001

Subject: [PATCH 06/21] video: gx1fb: remove unnecessary pci_set_drvdata()
The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
