[PATCH] crypto: sun4i-ss: erase key after use

When a TFM is unregistered, the sun4i-ss driver does not clean the key used, leaking it in memory. This patch adds this absent key cleaning. Fixes: 6298e948215f ("crypto: sunxi-ss - Add Allwinner Security System crypto accelerator") Cc: # 4.3+ Signed-off-by: Corentin Labbe --- drivers/crypto/s
