Well, IS_ERR_OR_NULL() went into the kernel in December 2009: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=603c4ba96be998a8dd7a6f9b23681c49acdf4b64 so it should be in kernel version 2.6.33 and later. If you don't want to generate a patch for the media_build backward compatability build system, you can probably just patch your kernel header file or trivially hack the function it into drivers/staging/lirc/lirc_zilog.c to get past your current build error. But I suspect you'll run into more errors. When I make changes to a module (like lirc_zilog.c), I tend to use the latest kernel interfaces at the time of the changes. If you don't need lirc_zilog.ko built, then configure the build system to not build the module.
