Subject: [PATCH v8 2/3] HID: usbhid: Share USB device firmware node with child HID device
Date: Mon, 27 Feb 2023 08:07:57 -0600	[thread overview]
Message-ID: <20230227140758.1575-3-kaehndan@gmail.com> (raw)
In-Reply-To: <20230227140758.1575-1-kaehndan@gmail.com>

USB HID core now shares its fwnode with its child HID device.
Since there can only be one HID device on a USB interface, it is redundant
to specify a hid node under the USB device. This allows usb HID device
drivers to be described in firmware and make use of device properties.
