[PATCH 1/1] Char: mxser, fix ISA board lookup

From: Jiri Slaby

From: "Peter Botha" <peterb@xxxxxxxxxxxxxxxx>

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 it's 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.
