Hi Bhanu,
I love your patch! Yet something to improve:
[auto build test ERROR on chrome-platform-linux/for-next]
[also build test ERROR on soc/for-next ljones-mfd/for-mfd-next linus/master v5.8-rc2 next-20200625]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use as documented in
