I've just built a test kernel for a Thinkpad 775C. When it boots,
I get the above kernel message in the syslog repeated 12 times.

In my case, none of the IDE configuration is built modular, so requesting
the "ide-probe-mod" is the wrong thing to do, because it is already
compiled in.

    CONFIG_MODULES=y
    CONFIG_MODVERSIONS=y
    CONFIG_KMOD=y
    CONFIG_IDE=y
    CONFIG_BLK_DEV_IDE=y
    CONFIG_BLK_DEV_IDEDISK=y

I'm not sure of the best way to fix this, so no patch. However, here
are some thoughts.

    * Change ide.c:ide_probe_module to only request the module if
      CONFIG_KMOD and CONFIG_BLK_DEV_IDE_MODULE are true.
    * Change ide.c so that ideprobe_init() is called early, so ide_probe
      gets set before ide_probe_module is called.
    * Change ide-probe.c so that ide_probe_init is called early (similar to
      above).
