From f641ddddc3ad139a91b9a1f9cea84ea657f75a6b Mon Sep 17 00:00:00 2001 From: Martin Hicks Date: Tue, 3 Mar 2015 08:21:33 -0500 Subject: [PATCH] crypto: talitos - Simplify per-channel initialization There were multiple loops in a row, for each separate step of the initialization of the channels. Simplify to a single loop.
