2022-05-03ARM: dts: Group omap3 CM_CLKSEL_WKUP clocksTony Lindgren2-22/+37
The clksel related registers on omap3 cause unique_unit_address and node_name_chars_strict warnings with the W=1 or W=2 make flags enabled. With the clock drivers updated, we can now avoid most of these warnings by grouping the TI component clocks using the TI clksel binding, and with the use of clock-output-names property to avoid non-standard node names for the clocks.

Commit 3f6634d997db ("iommu: Use right way to retrieve iommu_ops") started triggering a NULL pointer dereference for some omap variants: __iommu_probe_device from probe_iommu_group+0x2c/0x38 probe_iommu_group from bus_for_each_dev+0x74/0xbc bus_for_each_dev from bus_iommu_probe+0x34/0x2e8 bus_iommu_probe from bus_set_iommu+0x80/0xc8 bus_set_iommu from omap_iommu_init+0x88/0xcc omap_iommu_init from do_one_initcall+0x44/0x24 This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV) as noted by Jason Gunthorpe <jgg@ziepe.ca>. Looks like the regression already happened with an earlier commit 6785eb9105e3 ("iommu/omap: Convert to probe/release_device() call-backs") that changed the function return type and missed converting one place.

2022-04-02tracing: mark user_events as BROKENSteven Rostedt (Google)3-0/+6
After being merged, user_events become more visible to a wider audience that have concerns with the current API. It is too late to fix this for this release, but instead of a full revert, just mark it as BROKEN (which prevents it from being selected in make config). Then we can work finding a better API. If that fails, then it will need to be completely reverted. To not have the code silently bitrot, still allow building it with COMPILE_TEST. And to prevent the uapi header from being installed, then later changed, and then have an old distro user space see the old version, move the header file out of the uapi directory. Surround the include with CONFIG_COMPILE_TEST to the current location, but when the BROKEN tag is taken off, it will use the uapi directory, and fail to compile. This is a good way to remind us to move the header back.
