[PATCH 1/4] dmaengine: dw_dmac: use helper macro module_platform_driver()

From: Andy Shevchenko
Date: Tue Oct 02 2012 - 07:42:27 EST


From: Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx>

Since v3.2 we have nice macro to define the platform driver's init and exit
calls. This patch simplifies the dw_dmac driver by using that macro.
