Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-next Thanks! [1/1] spi: spi-zynq-qspi: Fix some wrong goto jumps & missing error code commit: f131767eefc47de2f8afb7950cdea78397997d66 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 zynq_qspi_probe function, when enable the device clock is done, the return of all the functions should goto the clk_dis_all label. If num_cs is not right then this should return a negative error code but currently it returns success.
