Subject: [PATCH 3.16 14/99] crypto: pcrypt - Do not clear MAY_SLEEP flag
 in original request

3.16.84-rc1 review patch.  If anyone has any objections, please let me know.

------------------

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.
