Subject: [PATCH] drivers/nvme: fix pr_warn format string
Date:   Mon, 25 Jul 2022 12:17:51 -0700
Message-Id: <20220725191751.960838-1-jcmvbkbc@gmail.com>

Use %zu format instead of %lu to print variable of size_t type.
This fixes the following gcc build error on 32-bit targets:

  error: format '%lu' expects argument of type 'long unsigned int',
  but argument 3 has type 'size_t' {aka 'unsigned int'}

Fixes: 71ebe3842ebe ("nvmet-auth: Diffie-Hellman key exchange support")
