From 9a61bf6300533d3b64d7ff29adfec00e596de67d Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 18 Jan 2006 23:19:26 +0100 Subject: [PATCH] hwmon: Semaphore to mutex conversions convert drivers/hwmon/*.c semaphore use to mutexes. the conversion was generated via scripts, and the result was validated automatically via a script as well. all affected hwmon drivers were build-tested.
