After splitting platform and reworking PCI drivers the module
reloading became broken as reported by Hao. Here is the patch
to fix that along with another one that fixes PM runtime workflow
differences between the busses (PCI vs. platform).
This is material for v6.11 as the initial work landed there and we still
have time to fix it before the release.

In other cases we override it, and module remove and probe cycle will crash the kernel since it will carry a stale pointer. Fix this by supplying a third argument to the pxa2xx_spi_probe() and avoid overriding dev->platform_data.

In this case if we try enable it again the PM runtime complaints with pxa2xx_spi_pci 0000:00:07.0: Unbalanced pm_runtime_enable!

[1/2] spi: pxa2xx: Do not override dev->platform_data on probe commit: 9a8fc292dd93b93db30e01c94c0da4c944852f28 [2/2] spi: pxa2xx: Move PM runtime handling to the glue drivers commit: e17465f78eb92ebb4be17e35d6c0584406f643a0 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 ^ permalink raw reply [flat|nested] 6+ messages in thread
