Subject: [PATCH v2 0/2] spi: add devm_spi_optimize_message() helper

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.

---
Changes in v2:
- Dropped already applied SPI patches.
- Added patch to fix missing EXPORT_SYMBOL_GPL.
- Link to v1: https://lore.kernel.org/r/20240621-devm_spi_optimize_message-v1-0-3f9dcba6e95e@baylibre.com
