No, it doesn't add anything useful at all.

I know PWM is probably pulse width modulation, but why would my kernel
need to care about this ? Why would I need drivers for it ?

Also, think about what happens with 'oldconfig'. You don't get to even
see 'the drivers below' until you've answered this question.

It couldn't be more opaque if it tried.
