Subject: [PATCH 3.16 030/305] power: supply: max8998-charger: Fix platform
 data retrieval

3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Tomasz Figa <tomasz.figa@...il.com>

commit cb90a2c6f77fe9b43d1e3f759bb2f13fe7fa1811 upstream.

Since the max8998 MFD driver supports instantiation by DT, platform data
retrieval is handled in MFD probe and cell drivers should get use
the pdata field of max8998_dev struct to obtain them.
