Subject: [PATCH 8/8] nvmem: core: Avoid useless iterations in nvmem_cell_get_from_lookup()
Date:   Sun,  6 Jan 2019 20:28:20 +0100
Message-Id: <20190106192820.12558-9-albeu@free.fr>

Precedence: bulk

Once the correct cell has been found there is no need to continue
iterating, just stop there. While at it replace the goto used to leave
the loop with simple break statements.
