Hi Mark and Grant, Heard from Linus Walleij that you Mark has been helping out merging spi patches, did not know that when sending out this series. Anyway, do you guys see any issues merging this?

Signed-off-by: Ulf Hansson ulf.hans...@linaro.org Why? It was removed in this commit, is it wrong? Linus, please read the previous thread on pl022. The long and short of it is that your commit 2fb30d1147c599f5657e8c62c862f9a0f58d9d99 (spi/pl022: enable runtime PM) is totally broken, and Michel came along trying to fix the resulting breakage by partially removing your commit in 6887237cd7da904184dab2750504040c68f3a080 (spi/pl022: fix spi-pl022 pm enable at probe). The reason why your commit is wrong is: pm_runtime_get_noresume(dev); pm_runtime_set_active(dev); pm_runtime_enable(dev); ret = pcdrv-probe(pcdev, id); So, adding this in spi-pl022 probe: + pm_runtime_enable(dev); + pm_runtime_resume(dev); makes the sequence: pm_runtime_get_noresume(dev); pm_runtime_set_active(dev); pm_runtime_enable(dev); pm_runtime_enable(dev); pm_runtime_resume(dev); which is absolute rubbish. Your commit should never have gone into any tree. The real answer is to revert both commits to get the driver back to a sane state, before then progressing with the driver in a sane manner.
