2.6.29-stable review patch. If anyone has any objections, please let us know.

------------------

From: Peter Botha <peterb@xxxxxxxxxxxxxxxx>

commit 96050dfb25966612008dcea7d342e91fa01e993c upstream.

There's a bug in the mxser kernel module that still appears in the
2.6.29.4 kernel.

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 tested this, and removing the !
fixes the problem.
