Subject[PATCH 3.19 58/75] dmaengine: dw: append MODULE_ALIAS for platform driver
Date
3.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

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.
