[PATCH 1/2] lp8788-charger: fix a parent device in _probe()

From: Kim, Milo
Date: Thu Jan 03 2013 - 01:30:26 EST

The lp8788-charger is a platform driver of lp8788-mfd.
The platform device is allocated when mfd_add_devices() is called
in lp8788-mfd.
On the other hand, 'lp->dev' is the i2c client device.

Therefore, this 'platform_device' is a proper parent device in case of
resource managed mem alloc and device kernel message.
