From 477527baf6a8d4c8652f979f0aa3546216635184 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Thu, 23 May 2013 19:18:39 +0900 Subject: USB: host: use platform_{get,set}_drvdata() Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure.
