Subject: [PATCH 4.4 099/192] [PATCH 103/135] s390/crypto: provide correct file mode at device register.

4.4-stable review patch.  If anyone has any objections, please let me know.

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

[ Upstream commit 74b2375e6767935e6d9220bdbc6ed0db57f71a59 ]

When the prng device driver calls misc_register() there is the possibility
to also provide the recommented file permissions. This fix now gives
useful values (0644) where previously just the default was used (resulting
in 0600 for the device file).
