From 997d3eaf02cad6fdb54bd6085c9a7c48ddd68a2d Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Wed, 14 Dec 2011 14:54:22 -0800 Subject: [PATCH] rtmutex-tester: convert sysdev_class to a regular subsystem After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel.
