Subject: Re: [PATCH] ISDN: mark as 32-bit only
Some suggestions on doing it better
- Clean up warnings in drivers/isdn by using long not int for the values
where we pass void * and cast to integer types. The code is ok (ok
passing the stuff this way isn't pretty but the code is valid). In all
the cases I checked out the right thing happens anyway but this removes
all the warnings.
