[alsa-devel] [PATCH 1/4] ASoC: pcm3008: Remove noisy version print
From: Mark Brown broonie@linaro.org
The version number has never been updated and the printk isn't based on any interaction with the device.

This is better from a device model point of view since we don't try to do things like instantiate the card until the required resources appear.
