As this is removing code...
However, if you pay attention to linux-kernel or linux-arm-kernel, you will
notice that I've sent a patch deprecating IS_ERR_OR_NULL() and I'm starting
to remove its use. IS_ERR_OR_NULL() creates more problems than it solves
because people don't think about what the hell they're doing with it, or
even whether it's appropriate to use it.
