From 2f24d159d5ac418c946e0d38ada46345753688b1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 15 Feb 2007 18:56:43 +0100 Subject: [PATCH] [ALSA] cmipci - Allow to disable integrated FM port The driver didn't allow to disable the integrated FM port (if available), and this annoyed people who don't want FM port. Now fm_port=0 disables the FM port unconditionally. fm_port=1 is used for enabling the integrated FM port (as default). Also fixed the documentation about this option. Fix ALSA bug#2491.
