Subject: Re: [PATCH v6] gpio/mpc8xxx: change irq handler from chained to
normal
Hi Hui,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on gpio/for-next]
[cannot apply to v5.3 next-20190925]
[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]
