Here is the announced patch.
Changes:
- Dropped support for AWE wavetable. The new awe_wave driver
(0.4.4) supports pnp itself. I hope it will be included in the kernel.
- Support for joystick dropped, it's not the place for it.
- If a device is already active before the
driver is loaded then it's current settings will
be used. this will allow the user to manually configure
each card via the /proc/isapnp interface if needed.
- The card is leaved in an active state if it was already
active when the module was loaded.
We still have a problem when sb.o module isinserted/removed
many times without removing sb_lib.o too: i get
the message too many mixer devices or something similar,
i hadn't the time to check it.
Christoph, could you please check?
