This allows to set CONFIG_W2SG0004_DEBUG which will
make the driver report more activities and it will turn on the

the hardware. Therefore we add it as an option to the driver
because we think it is of general use (and a little tricky to
add by system testers).

Normally it should be off.

I'd say say this does not belong in the kernel at all. And even if the
power-state test were to be allowed, most of the pr_debugs would
need to go. You really should be using dev_dbg and friends, which can
already be enabled selectively at run time using dynamic debugging.
