picking the first patch

[Harsha Vardhan]

Hello team ,

Sorry for a vague question.

So far I have spent a lot of time dreaming to be a kernel hacker without
doing much , but I realised its geting too late and now I want to pick my
first patch to work,

I have decided to address the TODO at drivers/staging/grebus/TODO :
" * Make pwm.c use the struct pwm_ops::apply instead of ::config,
::set_polarity,
  4   ::enable and ::disable."

To make sure this is a first good patch , I verified that there is traction
for this driver recently.

But I am not sure, let's say I change the code , how to test it ?

Any thoughts on whether I should just do a checkpatch.pl change as my first
patch ?

Thanks
Vardhan
