Hi Richa,

Nice work. You may like to do all the camel case at the same
time. You could limit yourself to just this file and structures it
touches if it is easier. That way when reviewers are reviewing
your patch they will see nice clean lines added (instead of lines with
camel case in them still).

This would be nicer like this;

-	if (pInitParam->setAllEngOff == 1) {
+	if (init_param->set_all_eng_off == 1) {

Good luck,
Tobin.
