[PATCH v4 5/5] acpi: battery_common: battery present status for INT3407

[Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>]

acpi_battery_get_status() will be called often to check if the battery is
present. This call sets status.battery_present field to return the status.
But When enumerated via DPTF power (INT3407), since this field will not be
set as this is not a battery but it will still set the status.present
field. So a check is added when hid is INT3407 check for the presence and
set the status.battery_present flag, so that the rest of the driver calls
don't fail looking for status.battery_present flag.
