From 616ad593fe37ef265e5cb1282db6ca264197ffb2 Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Sat, 21 Nov 2009 01:01:18 +0100 Subject: ALSA: opti-miro: remove snd_card pointer from snd_miro structure Remove the snd_card pointer from the snd_miro structure and do some small code improvements. Also, move Opti chipset detection before detection of the ACI mixer, so the mci_base value is set in one place only.
