[Patch v3] Replacing 0xff.. with correct DMA_xBIT_MASK

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Matthias Gehre <[email protected]>

Included is a patch to replace all occurences of 0xff..
in calls to function pci_set_dma_mask() and pci_set_consistant_dma_mask()
with the corresponding DMA_xBIT_MASK from linux/dma-mapping.h.
This patch was made against 2.6.15-git9.

Signed-off-by: Matthias Gehre <[email protected]>

---
Task was found on janitor.kernelnewbies.org
This is a new version of an early submitted patch.
The last version was made against 2.6.14.3 by accident.
Sorry for that! Triple checked now.
Please CC answer to me.

 When pci_set_dma_mask() is successful, and returns zero, the PCI layer
 saves away this mask you have provided.  The PCI layer will use this
