We append "Pen", "Pad", "Mouse", "Keyboard", "Consumer Control" or "System Control" suffix to the appropriate input node to match what the Wacom driver does and be more convenient for the user to know which one is which. Signed-off-by: Benjamin Tissoires <redacted> --- changes in v2: - completed the list with "Consumer Control" and "System Control" to force having a suffix to each input node on the Huion H610 Pro drivers/hid/hid-uclogic.c | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+)
