mxser_get_ISA_conf takes a ioaddress as its first argument, by passing the
not of the ioaddr, you're effectively passing 0 which means it won't be
able to talk to an ISA card.

I have a problem passing parameters if the parameters may contain wildcards and/or spaces, if those parameters are optional. Since this sounds pretty abstract, let's have a small example: The following shell script some_command.sh expects 2 or 3 arguments.
The ABI in the Linux kernel 2.6.28 and earlier on s390, powerpc, sparc64, and mips 64-bit platforms requires that a 32-bit argument in a 64-bit register was properly sign extended when sent from a user-mode application, but cannot verify this, which allows local users to cause a denial of service (crash) or possibly gain privileges via a crafted syst
ISR cannot return any value, also we cannot pass any argument to it.
But in Linux we use IRQ_NONE / IRQ_HANDLED because devices share IRQ line. So what is the main interrupt handler which donot return any value, also don't receive any argument and how it calls IRQ handlers?
