Hello Paul,

Thanks a lot for your feedback.

Since it is a tristate kconfig symbol, it can be built as a kernel module
but since there isn't a LPC subsystem, the platform device is registered
in the module_init() function. So, building as a module is trickier since
there won't be an uevent that can trigger a module auto-load based on the
modinfo aliases information.

One can of course force udev to load the module by adding to modules.conf
or such but I wonder if is better to change from tristate to boolean or
add to the help that it can be built as a module but auto-load does not
work in that case.

Best regards,
Javier
