Hi "Ramuthevar,Vadivel,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on robh/for-next]
[also build test WARNING on arm-soc/for-next linus/master linux/master v5.7-rc5 next-20200514]
[cannot apply to mtd/master]
[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]
