From 8483c06797b62dbddac800b555b2fa1c689dbb1c Mon Sep 17 00:00:00 2001 From: Nicolin Chen Date: Sun, 17 Dec 2017 18:52:01 -0800 Subject: ASoC: fsl_ssi: Cache pdev->dev pointer There should be no trouble to understand dev = pdev->dev. This can save some space to have more print info or save some wrapped lines. Signed-off-by: Nicolin Chen Tested-by: Maciej S. Szmigiero Reviewed-by: Maciej S.
