From 68832eb08751b4ce23e90bd90e9414a465a99da3 Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Thu, 30 Jul 2026 15:19:40 +0200 Subject: [PATCH] powerpc/kexec: Simplify kdump_extra_elfcorehdr_size() Return the size directly and drop the extra_sz variable to simplify kdump_extra_elfcorehdr_size(). The two warning paths now fall through to the existing return 0 at the end of the function.
