From 6480af4915d6ffb66afc39eee4e9e66cbf59b938 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik Date: Wed, 26 Oct 2016 21:41:44 +0200 Subject: [PATCH] power_supply: wm97xx_battery: use power_supply_get_drvdata As the power supply framework provides a way to store and retrieve private supply data, use it. In the process, change the platform data for wm97xx_battery from a container of a single struct wm97xx_batt_pdata to the direct point to wm97xx_batt_pdata.
