Pull spi fixes from Mark Brown: "This is quite a big set of fixes, almost all from Johan Hovold who is on an ongoing quest to clean up issues with probe and removal handling in drivers. There isn't anything too concerning here especially with the deregistration stuff which will very rarely get run in production systems since this is all platform devices in the SoC on embedded hardware, but it's all real issues which should be fixed. There's more in flight here. We also have a few other minor fixes, one from Felix Gu along the same lines as Johan's work and a couple of documentation things" * tag 'spi-fix-v7.1-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (23 commits) spi: fix controller cleanup() documentation spi: fix resource leaks on device setup failure spi: axiado: clean up probe return value spi: axiado: rename probe error labels spi: axiado: fix runtime pm imbalance on probe failure spi: orion: clean up probe return value spi: orion: fix clock imbalance on registration failure spi: orion: fix runtime pm leak on unbind spi: imx: fix runtime pm leak on probe deferral spi: mpc52xx: fix use-after-free on registration failure spi: Fix the error description in the `ptp_sts_word_post` comment spi: topcliff-pch: fix use-after-free on unbind spi: topcliff-pch: fix controller deregistration spi: orion: fix controller deregistration spi: mxic: fix controller deregistration spi: mpc52xx: fix use-after-free on unbind spi: mpc52xx: fix controller deregistration spi: cadence-quadspi: fix controller deregistration spi: cadence: fix controller deregistration spi: mtk-snfi: fix memory leak in probe ...

spi: fix resource leaks on device setup failure

2026-04-22T14:10:22+00:00

Johan Hovold says: Make sure to call controller cleanup() if spi_setup() fails while registering a device to avoid leaking any resources allocated by setup().

spi: axiado: fix runtime pm imbalance on probe failure

2026-04-22T14:05:51+00:00

Make sure that the controller is active before disabling clocks on late probe failure and on driver unbind to avoid a clock disable imbalance. Also make sure that the usage count is balanced on probe failure (e.g. probe deferral) so that the controller can be suspended when a driver is later bound. Note that the runtime PM state can only be set when runtime PM is disabled.
