Go ahead and remove the\nsun8i-ce support which is one of the only remaining ones.\n\nNote that the sun8i-ce support for hwrng remains in place.  That is the\ninterface that actually matters.\n\nAs usual for crypto_rng, this driver was also buggy: its ->generate()\nfunction had a use-after-free vulnerability due to using\nwait_for_completion_interruptible_timeout() without handling shutting\ndown the DMA operation if a signal is sent.  There's no point in fixing\nthis separately only to remove the code anyway, so this commit is marked\nwith Fixes and Cc stable."
