Subject: [PATCH] crypto: sun8i-ce - Fix big-endian read of t_common_ctl
Message-ID: <20200904081122.GA23618@gondor.apana.org.au>

The field t_common_ctl is supposed to be little-endian and indeed
when it is filled in we've already done a cpu_to_le32 on it.
However, in sun8i_ce_run_task it is taken as CPU-endian which is
obviously wrong on BE.  This patch fixes it.
