[PATCH] net: ieee802154: remove unnecessary spi_set_drvdata()

[PATCH] net: ieee802154: remove unnecessary spi_set_drvdata()

[Jingoo Han]

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.
