2022-01-06HID: hid-uclogic-params: Invalid parameter check in ↵José Expósito
uclogic_params_frame_init_v1_buttonpad The function performs a check on the hdev input parameters, however, it is used before the check. Initialize the udev variable after the sanity check to avoid a possible NULL pointer dereference.

2021-12-02HID: add hid_is_usb() function to make it simpler for USB detectionGreg Kroah-Hartman
A number of HID drivers already call hid_is_using_ll_driver() but only for the detection of if this is a USB device or not. Make this more obvious by creating hid_is_usb() and calling the function that way. Also converts the existing hid_is_using_ll_driver() functions to use the new call.

- Trust Panora support improvements from Cristian Klein
2021-01-08HID: uclogic: Improve support for Trust PanoraCristian Klein
After more discussions with the [libinput project][1], it has been determined that the uclogic driver provides better support for this tablet. Fortunately, the Trust Panora is physically and logically identical with the UGEE G5, despite having a different USB vendor and product ID.

Refactor and extract UC-Logic tablet initialization and parameter discovery into a module.
