Subject[patch 10/18] m68k: Some network drivers do not check the platform
From: Geert Uytterhoeven <geert@linux-m68k.org>

Some network drivers do not check whether they're actually running on the
correct platform, causing multi-platform kernels to crash if they are not.

Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>

when I'm talking to journalists I just say "programmer" or something like that.
