From 8b932c6af4430a3c48aa291f0df63f28298a4af2 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sun, 7 Sep 2025 15:36:01 -0700 Subject: [PATCH] hwmon: (k10temp) Rely on subsystem locking Attribute access is now serialized in the hardware monitoring core, so locking in the driver code is no longer necessary. Drop it.
