From b9d9c82b4d081feb464f62dfc786c8621d09ecd2 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Thu, 15 Jun 2006 15:31:56 +0200 Subject: [PATCH] Driver core: add generic "subsystem" link to all devices Like the SUBSYTEM= key we find in the environment of the uevent, this creates a generic "subsystem" link in sysfs for every device. Userspace usually doesn't care at all if its a "class" or a "bus" device. This provides an unified way to determine the subsytem of a device, regardless of the way the driver core has created it.
