[1/1] spi: hisi-kunpeng: Delete the dump interface of data registers in debugfs commit: 7430764f5a85d30314aeef2d5438dff1fb0b1d68 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

Due to the reading of FIFO during the dump of data registers in debugfs, if SPI transmission is in progress, it will be affected and may result in transmission failure. Therefore, the dump interface of data registers in debugfs is removed.
