Subject: [PATCH v2 2/8] spi: add to_spi_device helper
Date: Thu, 23 Dec 2021 17:03:58 +0100 [thread overview]
Message-ID: <20211223160404.119970-3-m.tretter@pengutronix.de> (raw)
In-Reply-To: <20211223160404.119970-1-m.tretter@pengutronix.de>
Port the helper to get the spi_device from the device_d from Linux.
This macro makes SPI device drivers look a bit nicer.
