Hi Jani,

I apologize to miss these checkpatch errors. I mistakenly used some 
older version of checkpatch script and couldn't get these.

Nevertheless I should have taken care of the warnings from the 
patchwork. I fully understand that onus is on the submitter of the 
series to fix all such warnings and checks, and I take full 
responsibility of this mistake.

Thank you for fixing these issues this time, and I assure you that I 
will take care in future and make sure that the checkpatch warnings are 
addressed.

Once again I apologize for the fault.

Thanks & Regards,

Ankit
