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.

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.
