- Revert "driver core: enforce device_lock for driver_match_device()": When a device is already present in the system and a driver is registered on the same bus, we iterate over all devices registered on this bus to see if one of them matches. If we come across an already bound one where the corresponding driver crashed while holding the device lock (e.g. in probe()) we can't make any progress anymore. Thus, revert and clarify that an implementer of struct bus_type must not expect match() to be called with the device lock held. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQS2q/xV6QjXAdC7k+1FlHeO1qrKLgUCaawGIAAKCRBFlHeO1qrK LmYsAP0XzV/dZVrEqU5AvchbcuZ7kfAKotj4wPUIAkoT3gzMcQEAqNm7Vaf2ulDs CS8XvRi0PX6inD1Oo3dqwb0rKjKfFwY= =GT+5 -----END PGP SIGNATURE----- Merge tag 'driver-core-7.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fix from Danilo Krummrich: - Revert "driver core: enforce device_lock for driver_match_device()": When a device is already present in the system and a driver is registered on the same bus, we iterate over all devices registered on this bus to see if one of them matches.
