ACPI/APEI: Unlock apei_iomaps_lock on error path
|
|
|
|
This causes deadlocks during early boot on hardware with broken/buggy
|
|
APEI implementations, such as a Dell Poweredge 2950 with the latest
|
|
currently available BIOS.

Don't use goto or another special error path, as handling the error
|
|
case in normal flow is quite simple.
