[1/1] spi: uniphier: Fix a bug that doesn't point to private data correctly commit: 23e3404de1aecc62c14ac96d4b63403c3e0f52d5 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

In uniphier_spi_remove(), there is a wrong code to get private data from the platform device, so the driver can't be removed properly. The driver should get spi_master from the platform device and retrieve the private data from it.
