H. Nikolaus Schaller 1e451977e1 power: supply: bq27xxx: restrict no-battery detection to bq27000 
There are fuel gauges in the bq27xxx series (e.g. bq27z561) which may in some
cases report 0xff as the value of BQ27XXX_REG_FLAGS that should not be
interpreted as "no battery" like for a disconnected battery with some built
in bq27000 chip.

So restrict the no-battery detection originally introduced by

    commit 3dd843e1c2 ("bq27000: report missing device better.")

to the bq27000.

There is no need to backport further because this was hidden before

	commit f16d9fb6cf ("power: supply: bq27xxx: Retrieve again when busy")
