Subject: [PATCH v2 01/12] iio: frequency: adrf6780: introduce struct device variable
Date: Mon, 23 Feb 2026 15:13:52 +0200 [thread overview]
Message-ID: <20260223131418.55414-2-antoniu.miclaus@analog.com> (raw)
In-Reply-To: <20260223131418.55414-1-antoniu.miclaus@analog.com>
Add struct device *dev local variable to simplify repeated &spi->dev
dereferences. Where spi is no longer needed beyond &spi->dev, replace
struct spi_device *spi with struct device *dev = &st->spi->dev.
No functional change.
