Subject: [PATCH v4 01/21] PM / devfreq: rockchip-dfi: Embed desc into private data struct
Date: Fri,  5 May 2023 13:38:36 +0200	[thread overview]
Message-ID: <20230505113856.463650-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20230505113856.463650-1-s.hauer@pengutronix.de>

No need for an extra allocation, just embed the struct
devfreq_event_desc into the private data struct.
