the little patch below (vs. 2.4.5-ac13) fixes a freeze which happens
when the maestro module was unloaded and a HWV button gets pushed
generating the interrupt. so this disables all irqs of that chip
on remove...

Ask for minor 0 I believe, then load the module then see what you got.

it doesnt apply to the current version of the maestro driver (2.4.5-ac)
however. I think it is clashing with the docking station support

fantastic, thanks lukas.
alan, can you throw this in -ac? I don't think it will cause problems
for people with nonstandard wiring on the hw vol pins (read: dell

hwv_input=1 requests the alternative HWV input pins to be used.
The maestro will generate in
