6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Henrik Grimler <redacted>
[ Upstream commit 2da28b059e0ddcd2e1956eeae383246207965573 ]
bq27z561 currently uses the AveragePower reg, 0x22, for reading both
AveragePower and AvailableEnergy. The technical reference manual does
not mention AvailableEnergy, and it does not make sense to read a
cumulative, always positive, property like AvailableEnergy from a rate
property like AveragePower. Set REG_AE as invalid to fix it.
