[PATCH v2] acpi: apei: remove the unused dead-code for SEA notification type

From: Dongjiu Geng
Date: Wed Sep 13 2017 - 06:39:57 EST


In current code logic, the two functions ghes_sea_add() and
ghes_sea_remove() are only called when CONFIG_ACPI_APEI_SEA
is defined. If not, it will return errors in the ghes_probe()
and not continue. If the probe is failed, the ghes_sea_remove()
also has no chance to be called.

Hence, remove the unnecessary handling when CONFIG_ACPI_APEI_SEA
is not defined.
