Subject: [PATCH 4.14 064/173] crypto: pcrypt - Do not clear MAY_SLEEP flag in original request

From: Herbert Xu <herbert@...dor.apana.org.au>

commit e8d998264bffade3cfe0536559f712ab9058d654 upstream.

We should not be modifying the original request's MAY_SLEEP flag
upon completion.  It makes no sense to do so anyway.

Reported-by: Eric Biggers <ebiggers@...nel.org>
Fixes: 5068c7a883d1 ("crypto: pcrypt - Add pcrypt crypto...")
