[PATCH 06/12] efi/cper: adopt estatus iteration helpers
Ahmed Tiba

Wed Dec 17 03:28:39 PST 2025
Switch the CPER printer and validator to the estatus_*() accessor
wrappers introduced by the new core. This is a mechanical change that
replaces the local acpi_hest_*() helpers with their aliases and keeps
the section iteration code shared ahead of the GHES conversion.
