From 02c3c4e7026b307a220132b59758432b6e7a0cac Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sun, 28 Jul 2024 07:09:54 -0700 Subject: [PATCH] hwmon: (max1619) Mask valid alarm bits Bit 0, 5, and 6 in the status register are reserved and, if set, do not indicate an alarm. Bit 7 is the 'busy' bit and also does not indicate an alarm. Mask the non-alarm bits to avoid reporting them to userspace.
