Hi Christian,
I used eclipse. The reason why I changed the indent is that the current indents are composed of tabs and spaces, and I will get style warning from checkpatch script when trying to submit it to gerrit, so I made the indents all tabs. In this case, should I still use the previous indents?
Regards,
Yong

Looks like you accidentally changed the indentation of the other
function parameters here. What editor do you use?
Please make sure that you only change the type, with that fixed the
patch is Reviewed-by: Christian König <christian.koenig at amd.com>.
