From da0dab5ecb5001f76e739e71ee199db4c61e7af2 Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Thu, 9 Sep 2010 12:18:35 +0200 Subject: [PATCH] ALSA: virtuoso: fix WM8766 register writes with MSB The check for the volume update latch bit was accidentally in the wrong function, where it would prevent the MSB from being written, instead of correctly ignoring it for cached values.
