[PATCH 13/13] nvmem: core: Avoid useless iterations in nvmem_cell_get_from_lookup()

From: Srinivas Kandagatla
Date: Mon Jan 28 2019 - 12:35:12 EST


From: Alban Bedel <albeu@xxxxxxx>

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.
