Rusty Russell a67ff6a540 ALSA: module_param: make bool parameters really bool 
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

/*
This driver should provide support for most Aztech AZT2320 based cards.
Several AZT2316 chips are also supported/tested, but autoprobe doesn't
work: all module option have to be set.
No docs available for us at Aztech headquarters !!! Unbelievable ...
No other help obtained.
Thanks to Rainer Wiesner <rainer.wiesner@01019freenet.de> for the WSS
activation method (full-duplex audio!).
