The patch was constructed by replacing all occurences of usbhid_submit_report() by its hid_hw_request() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. Finally, few drivers still depends on USB_HID. Many of them are requiring the io wait callback.

The patch was constructed by replacing all occurences of usbhid_wait_io() by its hid_hw_wait() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. As of today, few drivers are still requiring an explicit USB layer dependency: * ntrig (a patch is on its way) * multitouch (one patch following and another on its way) * lenovo tpkbd * roccat * sony The last three are two deeply using direct calls to the usb subsystem to be able to be cleaned right now.

This patch separates struct hid_device's driver_lock into two. The goal is to allow hid device drivers to receive input during their probe() or remove() function calls. This is necessary because some drivers need to communicate with the device to determine parameters needed during probe (e.g., size of a multi-touch surface), and if possible, may perfer to communicate with a device on host-initiated disconnect (e.g., to put it into a low-power state). Historically, three functions used driver_lock: - hid_device_probe: blocks to acquire lock - hid_device_remove: blocks to acquire lock - hid_input_report: if locked returns -EBUSY, else acquires lock This patch adds another lock (driver_input_lock) which is used to block input from occurring. The lock behavior is now: - hid_device_probe: blocks to acq. driver_lock, then driver_input_lock - hid_device_remove: blocks to acq. driver_lock, then driver_input_lock - hid_input_report: if driver_input_lock locked returns -EBUSY, else acquires driver_input_lock This patch also adds two helper functions to be called during probe() or remove(): hid_device_io_start() and hid_device_io_stop(). These functions lock and unlock, respectively, driver_input_lock; they also make a note of whether they did so that hid-core knows if a driver has changed the lock state. This patch results in no behavior change for existing devices and drivers. However, during a probe() or remove() function call in a driver, that driver may now selectively call hid_device_io_start() to let input events come through, then optionally call hid_device_io_stop() to stop them.

Historically, logitech-dj communicated with the device during probe() to query the list of devices attached. Later, a change was introduced to hid-core that prevented incoming packets for a device during probe(), as many drivers are unable to handle such input. That change broke the device enumeration in logitech-dj, so commit 596264082f10dd4a56 was introduced to workaround that by waiting for normal input before enumerating devices. Now that drivers can opt-in to receive input during probe, this patch changes logitech-dj to do that, so that it can successfully complete enumeration of devices during probe().
