dmaengine: ioatdma: fix zero day warning on incompatible pointer type
The 32bit build is creating this warning. Since we don't expect anyone actually use this on 32bit, restrict ioatdma to be built only on x86_64. This issue has long existed and only reason it's surfacing due to code refactoring. drivers/dma/ioat/dma.c: In function 'ioat_timer_event': >> drivers/dma/ioat/dma.c:870:39: warning: passing argument 2 of 'ioat_cleanup_preamble' from incompatible pointer type if (ioat_cleanup_preamble(ioat_chan, &phys_complete)) ^ drivers/dma/ioat/dma.c:577:13: note: expected 'u64 *' but argument is of type 'dma_addr_t *' static bool ioat_cleanup_preamble(struct ioatdma_chan *ioat_chan, ^ Signed-off-by: Dave Jiang <dave.jiang@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
