Subject: Re: [PATCH v6 3/3] hwmon: (adt7475) Add support for configuring
initial PWM state
Hi Chris,
kernel test robot noticed the following build errors:
[auto build test ERROR on groeck-staging/hwmon-next]
[also build test ERROR on linus/master v6.10 next-20240719]
[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]
