From 339c8f2484a110fd94af4d045e2be9bf25800381 Mon Sep 17 00:00:00 2001 From: Frank Crawford Date: Sun, 30 Apr 2023 14:50:32 +1000 Subject: hwmon: (it87) Allow for chips with only 4 temp sensors Some chips are known to only have 4 temperature sensors and there is no requirement to test for more. Currently only the IT8622E fits this category.
