bcma: don't register devices disabled in OF

2025-12-01T10:43:34+00:00

[ Upstream commit a2a69add80411dd295c9088c1bcf925b1f4e53d7 ] Some bus devices can be marked as disabled for specific SoCs or models. Those should not be registered to avoid probing them.

PCI: Rename CRS Completion Status to RRS

2024-09-11T00:52:30+00:00

PCIe r6.0 changed the abbreviation for "Configuration Request Retry Status" Completion Status from "CRS" to "RRS" and uses the terminology of "Configuration RRS Software Visibility" instead of "CRS Software Visibility". Align the Linux usage with the r6.0 spec language. No functional change intended. It's confusing to make this change, but I think "RRS" *is* a better abbreviation because it was easy to interpret "CRS" as "Completion Retry Status", which really didn't make any sense.

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

2024-07-03T13:16:54+00:00

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.

bcma: convert to platform remove callback returning void

2024-03-12T15:32:55+00:00

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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

bcma: make bcma_bus_type const

2024-02-06T18:07:35+00:00

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

The uevent() callback in struct bus_type should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.
