Is there any reason to make this change ?

This is clean up.

This fixes the PCI state in the error path.

And this sets up the missing sysfs stuff.



It seem that these two patches for Kernel 2.6 were lost when au88x0 migrate from alsa-driver to alsa-kernel.


You're right.  It seems dropped at that time accidentally.

Could you care to post a patch to fix them?

These are the two patches lost during au88x0 migrate from alsa-driver to alsa-kernel.

* fixed the DMA allocation.
  pci_set_dma_mask() is called together with pci_set_consistent_dma_mask().
  also clean up the double check of mask.

* added snd_card_set_dev() macro.
* sysfsfied more pci, isapnp and usb drivers.
