Subject: [PATCH v5 02/25] PM / devfreq: rockchip-dfi: Embed desc into private data struct
Date: Wed, 24 May 2023 10:31:30 +0200 [thread overview]
Message-ID: <20230524083153.2046084-3-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230524083153.2046084-1-s.hauer@pengutronix.de>
No need for an extra allocation, just embed the struct
devfreq_event_desc into the private data struct.
