6.15-stable review patch. If anyone has any objections, please let me know.

From: Armin Wolf W_Armin@gmx.de
[ Upstream commit 94a370fc8def6038dbc02199db9584b0b3690f1a ]
The ACPI sysfs code will fail to initialize if acpi_kobj is NULL, together with some ACPI drivers.
Follow the other firmware subsystems and bail out if the kobject cannot be registered.
