From 6b583a64fd1e019fd01626b46892ebf2361951c5 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 27 Sep 2017 22:41:26 +0200 Subject: rtc: ds1307: simplify hwmon config We don't have to define an extra config symbol, IS_REACHABLE does what we need. And having this config symbol just to save the few bytes of hwmon support on non-DS3231 chips isn't worth it IMO (especially as the symbol is set per default).
