[PATCH 0/2] nvmet-auth: fix some minor bugs

[Maurizio Lombardi]

First patch modifies nvmet_auth_host_hash() so it correctly returns
the error code to its caller.

The second patch replaces a pr_debug() with pr_err().

Maurizio Lombardi (2):
  nvmet-auth: return the error code to the nvmet_auth_host_hash()
    callers
  nvmet-auth: replace pr_debug() with pr_err() to report an error.

[Maurizio Lombardi]

be returned to its callers.

[PATCH 2/2] nvmet-auth: replace pr_debug() with pr_err() to report an error.

[Maurizio Lombardi]

In nvmet_auth_host_hash(), if a mismatch is detected in the hash length
the kernel should print an error.
