From 568c59e722da22c9b0a485c2f1aaf28cb1b36b79 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 22 Sep 2008 08:56:01 +0200 Subject: [PATCH] ALSA: oxygen: add probe callback Add a probe callback to the model structure so that model-specific drivers can refine their model detection before the card is initialized.
