Subject: [PATCH 1/2] modpost: refactor check_sec_ref()
Date: Sun,  1 Oct 2023 14:47:35 +0900	[thread overview]
Message-ID: <20231001054736.1586001-1-masahiroy@kernel.org> (raw)

We can replace &elf->sechdrs[i] with &sechdrs[i] to slightly shorten
the code because we already have the local variable 'sechdrs'.

However, defining 'sechdr' instead shortens the code further.
