USB: mark all struct bus_type as const

2023-03-23T12:22:00+00:00

Now that the driver core can properly handle constant struct bus_type, move all of the USB subsystem struct bus_type structures as const, placing them into read-only memory which can not be modified at runtime.

driver core: make struct bus_type.uevent() take a const *

2023-01-27T12:45:52+00:00

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.

USB: core: Disable remote wakeup for freeze/quiesce

2022-04-23T08:33:52+00:00

The PM_EVENT_FREEZE and PM_EVENT_QUIESCE messages should cause the device to stop generating interrupts. USB core was previously allowing devices that were already runtime suspended to keep remote wakeup enabled if they had gone down that way. This violates the contract with pm, and can potentially cause MSI interrupts to be lost. Change that so that if a device is runtime suspended with remote wakeups enabled, it will be resumed to ensure remote wakeup is always disabled across a freeze.

USB: core: rename usb_driver_claim_interface() data parameter

2021-03-23T11:39:39+00:00

It's been almost twenty years since the interface "private data" pointer was removed in favour of using the driver-data pointer of struct device. Let's rename the driver-data parameter of usb_driver_claim_interface() so that it better reflects how it's used.

USB: core: drop outdated interface-binding comment

It's been almost twenty years since USB drivers returned a data pointer from their probe routines in order to bind to an interface. Time to update the documentation for usb_driver_claim_interface().

usbcore: Check both id_table and match() when both available

2020-10-28T12:24:58+00:00

From: Bastien Nocera When a USB device driver has both an id_table and a match() function, make sure to check both to find a match, first matching the id_table, then checking the match() function. This makes it possible to have module autoloading done through the id_table when devices are plugged in, before checking for further device eligibility in the match() function.
