The alternative is to not worry about it and review the slow drip of
fixes that will occur as a result.  The issues I just fixed were built
up over years.  They won't get to that level again.

In my mind contributors should be compiling their submissions with W=1
enabled by default.  I'm fairly sure the auto-builders do this now.

That's good.

Once W=1 warnings are down to an acceptable level in the kernel as a
whole, we can provide some guidance in SubmittingPatches (or similar)
on how to enable them (hint: you add "W=1" on the compile line).

Enabling W=1 in the default build will only serve to annoy Linus IMHO.
If he wants them to be enabled by default, they wouldn't be W=1 in the
first place, they'd be W=0 which *is* the default build.

Just to add real quick - my advice is to enable them for yourself and
send back any issues along with your normal review.  A W=1 issue is no
different to a semantic or coding style one.

I'd like to enable it for only files under drivers/clk/ but it doesn't
seem to work. I'm not asking to enable it at the toplevel Makefile. I'm
asking to enable it for drivers/clk/ so nobody has to think about it now
that you've done the hard work of getting the numbers in this directory
down to zero or close to zero.
