Go ahead and remove the\nsun8i-ss support which is one of the only remaining ones.\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.  Also, it had a buffer\noverread bug in the line 'memcpy(ctx->seed, d + dlen, ctx->slen);'.\nThere's no point in fixing these bugs separately only to remove the code\nanyway, so this commit is marked with Fixes and Cc stable."
