That's the merge commit for the branch, not the affected commit.

This patch adds a devm_spi_optimize_message() helper to simplify this common pattern. ---------------------------------------------------------------- David Lechner (3): Documentation: devres: add missing SPI helpers spi: add devm_spi_optimize_message() helper spi: add EXPORT_SYMBOL_GPL(devm_spi_optimize_message) Documentation/driver-api/driver-model/devres.rst | 3 +++ drivers/spi/spi.c | 28 ++++++++++++++++++++++++ include/linux/spi/spi.h | 2 ++ 3 files changed, 33 insertions(+)
