Subject: input: i8042: build failure on powerpc

Hello

I have made a random .config for testing my powerpc cross-compiler and I got this fail:

it seems that kb_data and kb_cs (declared as extern in drivers/input/serio/i8042-ppcio.h) are defined anywhere.

In general it helps to provide the broken configuration.

If you do some digging, you may notice that this has been broken
since commit 917f0af9e5a9 ("powerpc: Remove arch/ppc and include/asm-ppc"),
or in other words since 2008. CONFIG_INPUT is not set with walnut_defconfig,
which may explain why no one noticed.

I would suggest to just remove the offending code. Quite obviously it is dead.

Just for be clear, you suggest that I make a patch for removing powerpc support of the i8042 driver ?
I have add [email protected] to the discution.
