From 5c0e64dde80ffe78d930db4e38e6218598aecd85 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 8 Nov 2022 15:50:49 +0800 Subject: [PATCH] hwmon: (coretemp) Remove obsolete temp_data->valid Checking for the valid bit of IA32_THERM_STATUS is removed in commit bf6ea084ebb5 ("hwmon: (coretemp) Do not return -EAGAIN for low temperatures"), and temp_data->valid is set and never cleared when the temperature has been read once. Remove the obsolete temp_data->valid field.
