ASoC: cs35l35: Add local variable for dev in probe
Tidy up the code a little by adding a local variable for i2c_client->dev rather than referring to it explicitly everytime. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Acked-by: Brian Austin <brian.austin@cirrus.com> Signed-off-by: Mark Brown <broonie@kernel.org>
