Subject: ACPI: bus: Move acpi_arm_init() to the place of after acpi_ghes_init()
From: Hanjun Guo <guohanjun@xxxxxxxxxx>
commit d5921c460e543228d100daf67dac7a03dfaaa40a upstream.
acpi_agdi_init() in acpi_arm_init() will register a SDEI event, so
it needs the SDEI subsystem to be initialized (which is done in
acpi_ghes_init()) before the AGDI driver probing.
In commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific
initialisation into acpi_arm_init()"), the acpi_agdi_init() was
called before acpi_ghes_init() and it causes following failure:
| [ 0.515864] sdei: Failed to create event 1073741825: -5
| [ 0.515866] agdi agdi.0: Failed to register for SDEI event 1073741825
| [ 0.515867] agdi: probe of agdi.0 failed with error -5
| ...
| [ 0.516022] sdei: SDEIv1.0 (0x0) detected in firmware.
Fix it by moving acpi_arm_init() to the place of after
acpi_ghes_init().
