Subject: [PATCH net] ipw2x00: use DEVICE_ATTR_*() macro
Date:   Wed,  6 Apr 2022 09:54:44 +0800
Message-Id: <20220406015444.14408-1-tangmeng@uniontech.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Feedback-ID: bizesmtp:uniontech.com:qybgforeign:qybgforeign8
Precedence: bulk

Use DEVICE_ATTR_*() helper instead of plain DEVICE_ATTR,
which makes the code a bit shorter and easier to read.
