From 0a848680a82e47854347cdfecbe9adf8842719e6 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 6 Aug 2009 18:13:58 +0900 Subject: sound: request char-major-* module aliases for missing OSS devices Till now missing OSS devices emitted sound-slot/service-* module alises instead of the standard char-major-* if a missing device number is opened if soundcore is loaded. The custom module aliases don't have any inherent benefit than backward compatibility. sound-slot/service-* module aliases is scheduled to be removed and to help the transition this patch makes soundcore emit the standard module alises along with the custom ones.
