Subject: [PATCH 0/7] crypto: sun4i-ss: prevent always fallback for ciphers

Hello

For help testing on "crypto: sun4i-ss - Fix sparse endianness markers",
I have added "stats" support like other allwinner's crypto drivers.
Seeing stats showed a clear problem, the ciphers function were not used
at all.
This is due to the not-inialized need_fallback which is "init" as true
everytime.
So basicly, since the patch introduced it, this probem hidden some bugs.

This serie fixes all hidden problems, then fix the initialization of
"need_fallback" and then add the stats like other allwinner drivers.

Corentin Labbe (7):
  crypto: sun4i-ss: linearize buffers content must be kept
  crypto: sun4i-ss: checking sg length is not sufficient
  crypto: sun4i-ss: IV register does not work on A10 and A13
  crypto: sun4i-ss: handle BigEndian for cipher
  crypto: sun4i-ss: initialize need_fallback
  crypto: sun4i-ss: enabled stats via debugfs
  crypto: sun4i-ss: add SPDX header and remove blank lines
