commit 74b2375e6767935e6d9220bdbc6ed0db57f71a59 Author: Harald Freudenberger <fre...@linux.vnet.ibm.com> Date: Thu Mar 17 14:52:17 2016 +0100 s390/crypto: provide correct file mode at device register. 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).
