Subject[PATCH 4.14 424/496] max17042: propagate of_node to power supply device
Date
4.14-stable review patch.  If anyone has any objections, please let me know.

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

From: Pierre Bourdon <delroth@google.com>

[ Upstream commit 66ec32fc7cd116dab5c02603ea8ec28ff92da3b5 ]

max17042_get_status uses the core power_supply_am_i_supplied. That
function relies on DT properties to figure out the power supply
topology, and will error out without DT.

Fixes max17042 battery status being reported as "unknown".
