Subject: [PATCH v2 04/10] xhci: dbc: Use ATTRIBUTE_GROUPS()
Date: Mon, 16 Oct 2023 16:09:28 +0300 [thread overview]
Message-ID: <20231016130934.1158504-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20231016130934.1158504-1-andriy.shevchenko@linux.intel.com>
Embrace ATTRIBUTE_GROUPS() to avoid boiler plate code.
This should not introduce any functional changes.
