Subject: [PATCH 4.4 16/67] ALSA: usb-audio: Fix mixer ctl regression of Native Instrument devices
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@...e.de>
commit c4a359a0049f2e17b012b31e801e96566f6391e5 upstream.
The commit [da6d276957ea: ALSA: usb-audio: Add resume support for
Native Instruments controls] brought a regression where the Native
Instrument audio devices don't get the correct value at update due to
the missing shift at writing. This patch addresses it.
Fixes: da6d276957ea ('ALSA: usb-audio: Add resume support for Native Instruments controls')
