Subject: [PATCH 5.10 230/717] power: supply: max17042_battery: Fix current_{avg,now} hiding with no current sense

From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@...i.sm>

[ Upstream commit 4b0a56e692503692da6555337a697c17feabbb3e ]

When current sense is disabled, max17042_no_current_sense_psy_desc gets
used which ignores two last properties from the list.

Fixes: 21b01cc879cc ("power: supply: max17042_battery: Add support for the TTE_NOW prop")
