Subject[PATCH v2] ide: remove deprecated use of pci api
Date
Replace occurences of the pci api by appropriate call to the dma api.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr)

@deprecated@
idexpression id;
position p;
@@

(
pci_dma_supported@p ( id, ...)
|
pci_alloc_consistent@p ( id, ...)
)

@bad1@
idexpression id;
position deprecated.p;
@@
...when != &id->dev
when != pci_get_drvdata ( id )
when != pci_enable_device ( id )
(
pci_dma_supported@p ( id, ...)
|
pci_alloc_consistent@p ( id, ...)
)

@depends on !bad1@
idexpression id;
expression direction;
position deprecated.p;
@@

(
- pci_dma_supported@p ( id,
+ dma_supported ( &id->dev,
...
+ , GFP_ATOMIC
)
|
- pci_alloc_consistent@p ( id,
+ dma_alloc_coherent ( &id->dev,
...
+ , GFP_ATOMIC
)
)

Changes since v1:
- fold the two patches into one, GFP_ATOMIC is now replaced by
GFP_KERNEL
