This breaks the powerpc build on Fedora.

When building on ppc64 this commit causes the links of drivers/hwmon/lm93.o
to fail.

It introduces an undefined symbol
                 U .LM93_IN_FROM_REG

that isn't produced when this patch is reverted

This was found when the Fedora kernel failed to build when I pulled in
-rc5-git3.

can be seen at the end of:
http://koji.fedoraproject.org/koji/getfile?taskID=1582002&name=build.log

So can we revert this (at this stage in -rc5 or maybe fix it).

Dave.
