2021-07-21bus: Make remove callback return voidUwe Kleine-König1-1/+1
The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

class_create is actually defined at the header. Fix the markup there and add a new one at the right place. While here, also fix some markups for functions that have different names between their prototypes and kernel-doc comments.

2020-03-04driver core: Rename deferred_probe_timeout and make it globalJohn Stultz1-0/+1
Since other subsystems (like regulator) have similar arbitrary timeouts for how long they try to resolve driver dependencies, rename deferred_probe_timeout to driver_deferred_probe_timeout and set it as global, so it can be shared.
