ACPI / scan: Use acpi_bus_get_status() to initialize ACPI_TYPE_DEVICE devs
[ Upstream commit
63347db0affadcbccd5613116ea8431c70139b3e ]
The acpi_get_bus_status wrapper for acpi_bus_get_status_handle has some
code to handle certain device quirks, in some cases we also need this
quirk handling for the initial _STA call.
Specifically on some devices calling _STA before all _DEP dependencies
are met results in errors like these:
[ 0.123579] ACPI Error: No handler for Region [ECRM] (
00000000ba9edc4c)
[GenericSerialBus] (
20170831/evregion-166)
[ 0.123601] ACPI Error: Region GenericSerialBus (ID=9) has no handler
(
20170831/exfldio-299)
[ 0.123618] ACPI Error: Method parse/execution failed
\_SB.I2C1.BAT1._STA, AE_NOT_EXIST (
20170831/psparse-550)
acpi_get_bus_status already has code to avoid this, so by using it we
also silence these errors from the initial _STA call.
Note that in order for the acpi_get_bus_status handling for this to work,
we initialize dep_unmet to 1 until acpi_device_dep_initialize gets called,
this means that battery devices will be instantiated with an initial
status of 0. This is not a problem, acpi_bus_attach will get called soon
after the instantiation anyways and it will update the status as first
point of order.
