David or Jarkko, this patch is both trivial and obviously correct, please merge this into the keys tree for the next merge window else I'll take it via the LSM tree.

The declaration of keyring_read does not match the definition (security/keys/keyring.c). In this case the definition is correct because it matches what defined in "struct key_type::read" (linux/key-type.h). Fix the declaration removing the inconsistent __user annotation.
