Do you expect us to copy-paste similar feedback on each of them? This would not make any sense. Please organize all your submissions in a series with: git format-patch -32 git send-email ..... 00* The patches you sent were already sent before: https://lore.kernel.org/lkml/20200827185829.30096-1-krzk@kernel.org/ Best regards, Krzysztof

I see the same maintainers: Dmitry Torokhov + linux-input HWMON also appears because of usage of hwmon API inside, which might happen anyway for few other input drivers Best regards, Krzysztof

When possible use dev_err_probe help to properly deal with the PROBE_DEFER error, the benefit is that DEFER issue will be logged in the devices_deferred debugfs file. Using dev_err_probe() can reduce code size, and the error value gets printed.
