[PATCH 4.4 28/91] crypto: pcrypt - Do not clear MAY_SLEEP flag in original request

From: Greg Kroah-Hartman
Date: Thu Feb 13 2020 - 11:10:10 EST


From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>

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.
