Subject: Re: [PATCH] pinctrl: mediatek: add eint new design for mt8196
Hi chang,
kernel test robot noticed the following build errors:
[auto build test ERROR on linusw-pinctrl/devel]
[also build test ERROR on linusw-pinctrl/for-next linus/master v6.13-rc1 next-20241128]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
