Subject: [RFC][PATCH v5 07/51] objtool: mcount: Move nhdr into find_symtab()
Date: Thu, 18 Jun 2020 13:37:53 -0700	[thread overview]
Message-ID: <7bf31e46fa228ea4d8e47f4767b2c6f2e4180942.1592510545.git.mhelsley@vmware.com> (raw)
In-Reply-To: <cover.1592510545.git.mhelsley@vmware.com>

Since it's no longer needed in the rest of do_func() we can move
it to where it's needed rather than pass it as a parameter.
