Subject: Re: [PATCH] of_device: removed #include that caused a recursion in
 included headers

Hi Hadar,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on stm32/stm32-next]
[also build test ERROR on sunxi/sunxi/for-next tegra/for-next linus/master v5.7-rc1 next-20200413]
[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]
