From 9242e72aaea05c0fce2003a8efa48f403d87a5bf Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 28 Jul 2017 01:16:24 +0900 Subject: i2c: use dev_get_drvdata() to get private data in suspend/resume hooks Several drivers call to_platform_device() to get platform_device and pass it to platform_get_drvdata(). In platform_get_drvdata(), the platform_device is converted back to struct device again. Use dev_get_drvdata() to avoid platform_device/device dance.
