The find.h APIs are designed to be used only on unsigned long arguments. This can technically result in a over-read, but it is harmless in this case.

2021-12-16iio: iio_device_alloc(): Remove unnecessary self drvdataLars-Peter Clausen
Drvdata is typically used by drivers to attach driver specific data to a device. It is used to retrieve driver specific information when only the device to which the data is attached is available. In the IIO core in the `iio_device_alloc()` function we call `iio_device_set_drvdata(indio_dev, indio_dev)`. This sets the drvdata of the IIO device to itself. This is rather unnecessary since if we have a pointer to the IIO device to call `iio_device_get_drvdata()` on it we don't need to call the function since we already have the pointer. If we only have a pointer to the `struct device` we can use `dev_to_iio_dev()` to get the IIO device from it. Furthermore the drvdata is supposed to be reserved for drivers, so it should not be used by the IIO core in the first place. The `set_drvdata()` has been around from the very beginning of the IIO framework and back then it was used in the IIO device sysfs attribute handling code. But that was subsequently replaced with a `dev_to_iio_dev()` in commit e53f5ac52ec1 ("iio: Use dev_to_iio_dev()") and other cleanups. The self `set_drvdata()` is now no longer needed and can be removed. Verified that there no longer any users by checking for potential users using the following two coccinelle scripts and reviewing that none of the matches are problematic code. <smpl> @@ struct iio_dev *iio_dev; expression dev; identifier fn !~ "(remove|resume|suspend)"; @@ fn(...) { ... *iio_dev = dev_get_drvdata(dev) ... } </smpl> <smpl> @r1@ position p; struct iio_dev *indio_dev; identifier dev_fn =~ "^dev_"; identifier devm_fn =~ "^devm_"; @@ ( dev_fn | devm_fn ) (&indio_dev@p->dev, ...) @@ struct iio_dev *indio_dev; position p != r1.p; @@ *&indio_dev@p->dev</smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2021-12-12iio:dac:ad5755: Switch to generic firmware properties and drop pdataJonathan Cameron
Lars pointed out that platform data can also be supported via the generic properties interface, so there is no point in continuing to support it separately. Hence squish the linux/platform_data/ad5755.h header into the c file and drop accessing the platform data directly. Done by inspection only. Mostly completely mechanical with the exception of a few places where default value handling is cleaner done by first setting the value, then calling the firmware reading function but and not checking the return value, as opposed to reading firmware then setting the default if an error occurs. Part of general attempt to move all of IIO over to generic device properties, both to enable other firmware types and to remove drivers that can be the source of of_ specific behaviour in new drivers.

2021-12-12iio: trigger: Fix a scheduling whilst atomic issue seen on tsc2046Jonathan Cameron
IIO triggers are software IRQ chips that split an incoming IRQ into separate IRQs routed to all devices using the trigger. When all consumers are done then a trigger callback reenable() is called. There are a few circumstances under which this can happen in atomic context. 1) A single user of the trigger that calls the iio_trigger_done() function from interrupt context. 2) A race between disconnecting the last device from a trigger and the trigger itself sucessfully being disabled. To avoid a resulting scheduling whilst atomic, close this second corner by using schedule_work() to ensure the reenable is not done in atomic context. Note that drivers must be careful to manage the interaction of set_state() and reenable() callbacks to ensure appropriate reference counting if they are relying on the same hardware controls. Deliberately taking this the slow path rather than via a fixes tree because the error has hard to hit and I would like it to soak for a while before hitting a release kernel.

2021-12-11Merge tag 'xfs-5.16-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linuxLinus Torvalds
Pull xfs fix from Darrick Wong: "This fixes a race between a readonly remount process and other processes that hold a file IOLOCK on files that previously experienced copy on write, that could result in severe filesystem corruption if the filesystem is then remounted rw. I think this is fairly rare (since the only reliable reproducer I have that fits the second criteria is the experimental xfs_scrub program), but the race is clear, so we still need to fix this. Summary: - Fix a data corruption vector that can result from the ro remount process failing to clear all speculative preallocations from files and the rw remount process not noticing the incomplete cleanup" * tag 'xfs-5.16-fixes-3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: xfs: remove all COW fork extents when remounting readonly

git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu Pull percpu fixes from Dennis Zhou: "This contains a fix for SMP && !MMU archs for percpu which has been tested by arm and sh. It seems in the past they have gotten away with it due to mapping of vm functions to km functions, but this fell apart a few releases ago and was just reported recently. The other is just a minor dependency clean up. I think queued up right now by Andrew is a fix in percpu that papers of what seems to be a bug in hotplug for a special situation with memoryless nodes.
