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. Touchscreen continues
to work fine, and I don't have any battery hooked up
to it either, so I'm not missing any functionality.
