Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next Thanks! [1/1] ARM/spi: spear: Drop PL022 num_chipselect commit: d570838efb6fb3154cbd08ab1b22d1f6442b1e78 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. Thanks, Mark

A previous refactoring moved the chip select number handling to the SPI core and we missed a leftover platform data user in the ST spear platform. The spear is not using this chipselect or PL022 for anything and should be using device tree like the rest of the platform so just delete the offending platform data.
