Normally, I'm a fan of that sort of thing. However, in this case, I
think it makes sense to have the #ifdefs right in the probe function; at
least for me, it makes it easier to understand what's going on. The
synaptics stuff is especially tricky; with a cursory glance over the
code, one might assume that all the synaptics functions disappear when
CONFIG_MOUSE_PS2_SYNAPTICS is unset. However, if the #ifdef's are in
the probe function, it's pretty clear that some synaptics functions
still get called even when CONFIG_MOUSE_PS2_SYNAPTICS is unset.
Just my opinion, anyways.
