  spi: add EXPORT_SYMBOL_GPL(devm_spi_optimize_message) (2024-06-24 21:25:57 +0100)

spi: add devm_spi_optimize_message() helper

Helper from David Lechner <dlechner@...libre.com>:

    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.
