Hi Jaroslav,
This patch updates PnP Card Services to support the ALSA drivers and should
make it possible for them to be converted.
It makes two key changes:
1.) PnP Cards can now have several pnp card drivers bound to them
2.) PnP Card Services now use manual attaching and detaching of drivers. As a
result, it can run card requests through the same code paths as regular drivers
and therefore the amount of code required to handle card drivers is
significantly reduced.
I would appreciate any comments.
Thanks,
Adam
