From: Emil Velikov <[email protected]> Currently only an authenticated master can authenticate another client.
In practise the client can only be master if CAP_SYS_ADMIN is present, although having the CAP also sets the client as authenticated. Thus DRM_AUTH in AUTH_MAGIC's "DRM_AUTH | DRM_MASTER" is superfluous. Notices while working on IGT tests.
