Subject: [PATCH 06/12] ASoC: rockchip: Remove unnecessary function call
Date: Sun, 20 Aug 2017 13:25:46 +0800	[thread overview]
Message-ID: <1503206746-15555-1-git-send-email-dolinux.peng@gmail.com> (raw)

First of all,the address of pdev->dev is assigned to card->dev,then
the function platform_set_drvdata copies the value the variable card
to pdev->dev.driver_data, but when calling snd_soc_register_card,the
function dev_set_drvdata(card->dev, card) will also do the same copy
operation,so i think that the former copy operation can be removed.
