Hi Pradeep,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on ath6kl/ath-next]
[also build test ERROR on next-20200529]
[cannot apply to v5.7-rc7]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
