Subject: [PATCH v3 0/2] spi: add devm_spi_optimize_message() helper
Date: Mon, 24 Jun 2024 15:46:06 -0500 [thread overview]
Message-ID: <20240624-devm_spi_optimize_message-v3-0-912138c27b66@baylibre.com> (raw)
In the IIO subsystem, we are finding that it is common to call
spi_optimize_message() during driver probe since the SPI message
doesn't change for the lifetime of the driver. This patch adds a
devm_spi_optimize_message() helper to simplify this common pattern.
