[PATCH 13/31] acpi/ghes: better name the offset of the hardware error firmware

Mauro Carvalho Chehab
2024-12-06T17:21:28Z

The etc/hardware_errors fw_cfg file is where the HEST error
source structures store registers pointed by Generic Address
Structures, as defined at:

https://uefi.org/specs/ACPI/6.5/18_Platform_Error_Interfaces.html#generic-error-data-entry

and

https://uefi.org/specs/ACPI/6.5/18_Platform_Error_Interfaces.html#generic-hardware-error-source-version-2-ghesv2-structure

As the name of the firmware file is hardware_errors, better
name the variable where the offset pointing to it will be stored
from ghes_error_le to hw_error_le.

No functional changes.
