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

From: arnd@arndb.de (Arnd Bergmann)
Date: 2016-02-18 14:05:05
Also in: lkml
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

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.
