I'm trying to replace consistent_alloc in a driver that was written for
the 2.4 kernel with dma_alloc_coherent. My question is that I do not use
a struct device * pointer at all. Browsing through the source for the
2.6.12
on ARM XScale PXA255, I see that this argument may be NULL.
Still, I'd like to know if passing NULL has any side effects. If so,
what are they?
I do however have a cdev structure taht I use for device registration,
but I do not see how that would help.
What kind of a device is it? If it's a PCI device, the struct device can
be accessed with the dev pointer inside the struct pci_dev.
