Subject: [patch 1/1] drivers/block/sx8.c: Use the DMA_{64, 32}BIT_MASK constants
Date: Sat, 19 Mar 2005 14:18:03 +0100 [thread overview]
Message-ID: <20050319131803.E8BAE1F23D@trashy.coderock.org> (raw)
Use the DMA_{64,32}BIT_MASK constants from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask()
These patches include dma-mapping.h explicitly because it caused errors
on some architectures otherwise.
See http://marc.theaimsgroup.com/?t=108001993000001&r=1&w=2 for details
