Subject: crypto: talitos - Simplify per-channel initialization
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f641ddddc3ad139a91b9a1f9cea84ea657f75a6b;p=linux-beck.git

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.
