Corentin LABBE	a80e1fbf11	crypto: sun4i-ss - Replace spinlock_bh by spin_lock_irq{save|restore} ... commit bdb6cf9f6fe6d9af905ea34b7c4bb78ea601329e upstream. The current sun4i-ss driver could generate data corruption when ciphering/deciphering. It occurs randomly on end of handled data. No root cause have been found and the only way to remove it is to replace all spin_lock_bh by their irq counterparts.

LABBE Corentin	9da75de030	crypto: sunxi-ss - Fix a possible driver hang with ciphers ... The sun4i_ss_opti_poll function cipher data until the output miter have a length of 0. If the crypto API client, give more SGs than necessary this could result in an infinite loop. Fix it by checking for remaining bytes, just like sun4i_ss_cipher_poll().
