From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit a104a45ba7a51b5b4c5e8437020d9d48edf22f89 upstream.
The commit 9cade1a46c77 (dma: dw: split driver to library part and platform
code) introduced a separate platform driver but missed to add a
MODULE_ALIAS("platform:dw_dmac"); to that module.
The patch adds this to get driver loaded automatically if platform device is
registered.
