From 29998d24ab5ec488cd127488246cc749b0ac52d6 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 30 Jul 2007 08:14:31 +0200 Subject: [ALSA] check for linked substreams of different cards It is possible to have linked substreams that belong to different cards and/or different drivers. This patch changes some drivers to make sure that they do not incorrectly try to handle substreams of a different card.
