Subject: [PATCH v3 3/7] common: elf: split init to be reused from other function
Date: Tue, 28 Apr 2020 09:50:56 +0200	[thread overview]
Message-ID: <20200428075100.17565-4-cleger@kalray.eu> (raw)
In-Reply-To: <20200428075100.17565-1-cleger@kalray.eu>

New elf_open function will also need to initialize an elf file. Split
this to avoid missing members initialization.
