Subject: Re: [PATCH v1 2/2] gpio: wcd934x: Use proper headers and drop
OF_GPIO dependency
Hi Andy,
I love your patch! Perhaps something to improve:
[auto build test WARNING on brgl/gpio/for-next]
[also build test WARNING on linus/master v6.2-rc3 next-20230112]
[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
https://git-scm.com/docs/git-format-patch#_base_tree_information]
