Don't add this blank line.

You won't detect this by running checkpatch on the patch, but if you
apply the patch and re-run checkpatch on the file then it will complain
about this.

Do we need the else?  Could be written as:

	if (iep->pps_enabled)
		icss_iep_pps_enable(iep, false);
	if (iep->perout_enabled)
		icss_iep_perout_enable(iep, NULL, false);
