+Subject: [PATCH 65/73] ACPI/AC: prevent OOPS on some boxes due to missing
+ check power_supply_register() return value check
+
+commit f197ac13f6eeb351b31250b9ab7d0da17434ea36 upstream.
+
+In the ac.c, power_supply_register()'s return value is not checked.
+
+As a result, the driver's add() ops may return success
+even though the device failed to initialize.
+
+For example, some BIOS may describe two ACADs in the same DSDT.
+The second ACAD device will fail to register,
+but ACPI driver's add() ops returns sucessfully.
+The ACPI device will receive ACPI notification and cause OOPS.
