From 3f5c34c6d4688b3b7e1dbc7bbc68a2f03a0d6b0c Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Tue, 24 Jan 2017 10:12:00 -0800 Subject: [PATCH] Input: wm97xx - make missing platform data non-fatal Commit 6480af4915d6 ("power_supply: wm97xx_battery: use power_supply_get_drvdata") made wm97xx platform data mandatory, although it's still optional. This patch fixes an oops during driver probe on one of my MIPS boards with a wm9712.
