[PATCH 25/29] mv_xor: remove hw_id field from platform_data
From: Thomas Petazzoni <hidden>
Date: 2012-11-15 17:20:30
Subsystem:
arm port, arm/marvell dove/mv78xx0/orion soc support, dma generic offload engine subsystem, the rest · Maintainers:
Russell King, Andrew Lunn, Sebastian Hesselbarth, Gregory Clement, Vinod Koul, Linus Torvalds
There is no need for the platform_data to give this ID, it is simply the channel number, so we can compute it inside the driver when registering the channels.
