From 991f9fa90360b64e8b79688d8ab0f034983a959d Mon Sep 17 00:00:00 2001 From: Matt Ranostay Date: Sun, 24 Jul 2016 17:05:32 -0700 Subject: [PATCH] hwmon: (sht3x) set initial jiffies to last_update Handling the wraparound requires the data->last_update to be set to an initial jiffies value. Otherwise on 32-bit systems you will not be able to request a reading till the 5 minute jiffies rollover happens.
