Subject: [PATCH] dax: Remove usage of the deprecated ida_simple_xxx API
Date:   Sun, 25 Sep 2022 21:26:35 -0400
Message-ID: <20220926012635.3205-1-liubo03@inspur.com>
MIME-Version: 1.0
Content-Type: text/plain
tUid:   20229260926398113c515f49a2a58b7974007982becac
Abuse-Reports-To: service@corp-email.com
Precedence: bulk

Use ida_alloc_xxx()/ida_free() instead of
ida_simple_get()/ida_simple_remove().
The latter is deprecated and more verbose.
