staging: fieldbus: Delete unused driver

2024-11-03T23:53:07Z

Sven Van Asbroeck contributed this driver in 2019. The following reasons lead to the removal: - This driver generates maintenance workload - only 11 patches during the last 3 years. Part of the patches seem to be motivated because of maintenance (for example - remove deprecated function) - Maintainer lost interest, last "Reviewed-by:" is May 2021 - no blog about usage of this driver The staging subsystem is the way for drivers into the kernel - at current speed and interest this is never going to happen. I think that fieldbus is an interesting topic. But when almost nobody cares about this driver, it does not make sense to keep it. Please consider that support will remain for years in the longterm kernels.

staging: Switch back to struct platform_driver::remove()

2024-10-09T09:54:53Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all staging drivers to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

driver core: have match() callback in struct bus_type take a const *

2024-07-03T13:16:54Z

In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

staging: fieldbus: make fieldbus_class constant

2024-03-05T14:02:33Z

Since commit 43a7206b0963 ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the fieldbus_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.

Now that the driver core can properly handle constant struct bus_type, move the anybus_bus variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

staging: fieldbus: Remove usage of the deprecated ida_simple_xx() API

2024-01-24T18:19:47Z

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_max() is inclusive. So a -1 has been added when needed.
