[ Upstream commit c35e03eaece71101ff6cbf776b86403860ac8cc3 ]
The crypto completion function currently takes a pointer to a
struct crypto_async_request object. However, in reality the API
does not allow the use of any part of the object apart from the
data field. For example, ahash/shash will create a fake object
on the stack to pass along a different data field.
This leads to potential bugs where the user may try to dereference
or otherwise use the crypto_async_request object.
This patch adds some temporary scaffolding so that the completion
function can take a void * instead. Once affected users have been
converted this can be removed.
The helper crypto_request_complete will remain even after the
conversion is complete. It should be used instead of calling
the completion function directly.
