From d56b9b9c464a10ab1ee51a4c6190a2b57b8ef7a6 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Wed, 4 Oct 2006 02:17:22 -0700 Subject: [PATCH] The scheduled removal of some OSS drivers This patch contains the scheduled removal of OSS drivers that: - have ALSA drivers for the same hardware without known regressions and - whose Kconfig options have been removed in 2.6.17.
