[PATCH 7/9] ARM: move NO_DMA definition to ecard.h

From: Arnd Bergmann
Date: Thu Feb 18 2016 - 09:05:09 EST


The NO_DMA macro is only used on the RiscPC ecard bus, and conflicts
with a couple of driver specific macros with the same name:

drivers/scsi/eata.c:571:0: warning: "NO_DMA" redefined
#define NO_DMA 0xff
In file included from ../drivers/scsi/eata.c:495:0:
arch/arm/include/asm/dma.h:140:0: note: this is the location of the previous definition
#define NO_DMA 255

This moves the definition out of the asm/dma.h header that is used
by all ISA DMA API users and into the ecard header.
