| |
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.
