When gpio detection is not supplied, presence state transitions depend
on every smbus transfer result from get_property(). This patch tries to
check battery presence again with well supported command before
state transition.

Changes:
v3: check return value of get_presence_and_health()
v2: combine get_presence_and_health functions to reuse

Ikjoon Jang (2):
  power: supply: sbs-battery: combine get_presence_and_health
  power: supply: sbs-battery: don't assume i2c errors as battery
    disconnect
