Subject: [03/26] ASoC: Dont use wm8994->control_data in wm8994_readable_register()

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Brown <broonie@...nsource.wolfsonmicro.com>

commit 8eeea521d9d0fa6afd62df8c6e6566ee946117fa upstream.

The field is no longer initialised so this will crash if running on
wm8958.
