pnp: set the pnp_card dma_mask for use by ISAPnP cards 2008-07-26T19:00:02+00:00 Rene Herman rene.herman@keyaccess.nl 2008-07-26T02:44:42+00:00 e86b19ce64a25d39bb0e10e0e695213fc5993dfb dma_alloc_coherent() on x86 currently takes a passed in NULL device pointer to mean that it should allocate an ISA compatible (24-bit) buffer which is a bit of a hack. The ALSA ISA drivers are the main consumers of this but have a struct device in fact readily available. For the PnP drivers, the specific pnp_dev->dev device pointer is not always available at the right time so for now we want to pass the pnp_card->dev instead which is always available.

dma_alloc_coherent() on x86 currently takes a passed in NULL device
pointer to mean that it should allocate an ISA compatible (24-bit) buffer
which is a bit of a hack.

The ALSA ISA drivers are the main consumers of this but have a struct
device in fact readily available.

For the PnP drivers, the specific pnp_dev->dev device pointer is not
always available at the right time so for now we want to pass the
pnp_card->dev instead which is always available.  Set its dma_mask in
preparation for doing so.

This does not fix a current bug -- 2.6.26-rc1 stumbled over the NULL hack
in dma_alloc_coherent() but this has already been fixed in commit
4a367f3a9dbf2e7ffcee4702203479809236ee6e by Takashi Iwai.
