[PATCH 4/4] MFD: mcp-sa11x0: remove DMA initializers and variables

Russell King - ARM Linux linux at arm.linux.org.uk
Fri Jan 20 13:06:11 EST 2012


The dma_device_t variables are only ever written to by mcp-sa11x0 and
never read.  As the old SA11x0 DMA support will be removed, remove
these so that it no longer depends on the old SA11x0 DMA definitions.
