Subject: [PATCH v1 1/7] clk: bcm: rpi: Create helper to retrieve private data
Date: Mon, 15 Aug 2022 17:31:23 +0200 [thread overview]
Message-ID: <20220815-rpi-fix-4k-60-v1-1-c52bd642f7c6@cerno.tech> (raw)
In-Reply-To: <20220815-rpi-fix-4k-60-v1-0-c52bd642f7c6@cerno.tech>
The RaspberryPi firmware clocks driver uses in several instances a
container_of to retrieve the struct raspberrypi_clk_data from a pointer
to struct clk_hw. Let's create a small function to avoid duplicating it
all over the place.
