[patch 04/13] mtd: register orion_nand using platform_driver_probe()

[akpm at linux-foundation.org]

From: Uwe Kleine-König <u.kleine-koenig at pengutronix.de>

orion_nand_probe lives in .init.text, so using platform_driver_register to
register it is wrong because binding a device after the init memory is
discarded (e.g.  via sysfs) results in an oops.

As requested by Nicolas Pitre platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.  This
saves some memory, but devices registered after the driver is probed are
not bound (probably there are none) and binding via sysfs isn't possible.
