[PATCH v2 03/11] ASoC: cs42l42: Use cs42l42->dev instead of &i2c_client->dev

[Martin Povišer]

From: Richard Fitzgerald <rf at opensource.cirrus.com>

In preparation for splitting cs42l42_i2c_probe() into multiple functions
replace use of &i2c_client->dev with cs42l42->dev. This reduces diff
clutter in the patch that splits the function.
