-Subject: [PATCH] hwmon: raspberrypi: Prevent voltage low warnings from
- filling log
-
-Although the correct fix for low voltage warnings is to
-improve the power supply, the current implementation
-of the detection can fill the log if the warning
-happens freqently. This replaces the logging with
-slightly custom ratelimited logging.
