[PATCH] dw_dmac: call .probe after we have a device in place

[PATCH] dw_dmac: call .probe after we have a device in place

[Andy Shevchenko]

If we don't yet have the platform device for the driver when it is being loaded
we fail to probe the driver. So instead of calling probe() directly we call
platform_driver_register(). It will call the probe() immediately if we have the
device but also makes the driver to work on platforms where the platform device
is created later.
