Subject: Re: [PATCH 1/4] gpio: gpiolib: Allow GPIO IRQs to lazy disable

Hi Maulik,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on gpio/for-next]
[also build test ERROR on pinctrl/devel v5.7-rc6 next-20200522]
[cannot apply to tip/irq/core]
[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]
