2023-03-06spi: fsl-spi: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-03-05spi: Replace spi_pcpu_stats_totalize() macro by a C functionGeert Uytterhoeven
spi_pcpu_stats_totalize() is a rather large macro, and is instantiated 28 times, causing a large amount of duplication in the amount of generated code. Reduce the duplication by replacing spi_pcpu_stats_totalize() by a real C function, and absorb all other common code from spi_statistics_##name##_show(). As (a) the old "field" parameter was the name of a structure member, which cannot be passed to a function, and (b) passing a pointer to the member is also not an option, due to the loop over all possible CPUs, the "field" parameter is replaced by an "offset" parameter, pointing to a location within the structure. This reduces kernel size by ca. 4 KiB (on arm32 and arm64).

2023-03-05spi: rockchip: Add architecture dependencyMark Brown
If base support for Rockchip SoCs has been disabled then the SPI driver won't be terribly useful, add a dependency on ARCH_ROCKCHIP || COMPILE_TEST to avoid it appearing when not needed.

2023-03-05spi: mpc5xxx-psc: Use platform resources instead of parsing DT propertiesRob Herring
The mpc52xx-psc and mpc512x-psc drivers use DT property parsing functions for 'reg' and 'interrupts', but those are available as platform device resources. Convert probe functions to use them and simplify probe to a single function. For 'cell-index', also use the preferred typed property function.

2023-03-05spi: mpc5xxx-psc: Convert probe to use devres functionsRob Herring
Convert the mpc52xx-psc and mpc512x-psc drivers to use the managed devres variants of functions in probe. Also use dev_err_probe() as appropriate. With this, the error handling can be simplified.

There's a lot of changes this development cycle, most of the work falls into two different categories: - fw_devlink fixes and updates. This has gone through numerous review cycles and lots of review and testing by lots of different devices. Hopefully all should be good now, and Saravana will be keeping a watch for any potential regression on odd embedded systems. - driver core changes to work to make struct bus_type able to be moved into read-only memory (i.e. const) The recent work with Rust has pointed out a number of areas in the driver core where we are passing around and working with structures that really do not have to be dynamic at all, and they should be able to be read-only making things safer overall. This is the contuation of that work (started last release with kobject changes) in moving struct bus_type to be constant. We didn't quite make it for this release, but the remaining patches will be finished up for the release after this one, but the groundwork has been laid for this effort. Other than that we have in here: - debugfs memory leak fixes in some subsystems - error path cleanups and fixes for some never-able-to-be-hit codepaths. - cacheinfo rework and fixes - Other tiny fixes, full details are in the shortlog All of these have been in linux-next for a while with no reported problems" [ Geert Uytterhoeven points out that that last sentence isn't true, and that there's a pending report that has a fix that is queued up - Linus ] * tag 'driver-core-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (124 commits) debugfs: drop inline constant formatting for ERR_PTR(-ERROR) OPP: fix error checking in opp_migrate_dentry() debugfs: update comment of debugfs_rename() i3c: fix device.h kernel-doc warnings dma-mapping: no need to pass a bus_type into get_arch_dma_ops() driver core: class: move EXPORT_SYMBOL_GPL() lines to the correct place Revert "driver core: add error handling for devtmpfs_create_node()" Revert "devtmpfs: add debug info to handle()" Revert "devtmpfs: remove return value of devtmpfs_delete_node()" driver core: cpu: don't hand-override the uevent bus_type callback. devtmpfs: remove return value of devtmpfs_delete_node() devtmpfs: add debug info to handle() driver core: add error handling for devtmpfs_create_node() driver core: bus: update my copyright notice driver core: bus: add bus_get_dev_root() function driver core: bus: constify bus_unregister() driver core: bus: constify some internal functions driver core: bus: constify bus_get_kset() driver core: bus: constify bus_register/unregister_notifier() driver core: remove private pointer from struct bus_type ...
