[16/99] watchdog: Fix rio watchdog probe function

[Greg KH]

2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

[ Upstream commit 03717e3d12b625268848414e39beda25e4515692 ]

After sucessfully registering the misc device the driver iounmaps the
hardware registers and kfree's the device data structure. Ouch !

This was introduced with commit e42311d75 (riowatchdog: Convert to
pure OF driver) and went unnoticed for more than a year :)

Return success instead of dropping into the error cleanup code path.
