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
