Applied "spi: pxa2xx: Setup maximum supported DMA transfer length" to the spi tree

by Mark Brown

The patch spi: pxa2xx: Setup maximum supported DMA transfer length has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[PATCH] acpi/nfit: Fix bus command validation

by Dan Williams

Commit 11189c1089da "acpi/nfit: Fix command-supported detection" broke ND_CMD_CALL for bus-level commands. The "func = cmd" assumption is only valid for: ND_CMD_ARS_CAP ND_CMD_ARS_START ND_CMD_ARS_STATUS ND_CMD_CLEAR_ERROR The function number otherwise needs to be pulled from the command payload for: NFIT_CMD_TRANSLATE_SPA NFIT_CMD_ARS_INJECT_SET NFIT_CMD_ARS_INJECT_CLEAR NFIT_CMD_ARS_INJECT_GET Update cmd_to_func() for the bus case and call it in the common path.
