Fix compile of swim3 as module

The current pmac32_defconfig fails to build with the following error:

  Building modules, stage 2.
ERROR: "check_media_bay" [drivers/block/swim3.ko] undefined!
WARNING: modpost: Found 23 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
make[2]: *** [__modpost] Error 1

This patch fixes that.
