[PATCH] hwmon: (asus-ec-sensors) do not print from .probe()

From: Eugene Shalygin
Date: Thu Feb 17 2022 - 02:23:53 EST


Remove the call to dev_info() from the board detection function, which
is called from probe(), not only to be in line with hwmon driver rules, but
also because the message duplicates the error code returned from probe()
for that case (ENODEV).
