From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michal Rokos Date: Fri, 15 Oct 2004 12:34:53 +0000 Subject: [Patch 2.6] Sound - Exclude uneeded code when.CONFIG_PROC_FS Message-Id: <200410151434.53766.michal@rokos.info> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-sound@vger.kernel.org Cc: linux-kernel@vger.kernel.org Hello, I tried to compile without procfs support and I got few "unused code" warnings. This patch fixes it. Tested by compilation only.
