Subject: [PATCH] hwmon: Directly use ida_alloc()/free()
Date:   Tue, 17 May 2022 02:40:22 +0000
Message-ID: <20220517024022.1980274-1-liuke94@huawei.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

Use ida_alloc()/ida_free() instead of deprecated
ida_simple_get()/ida_simple_remove() .
