[Huion/Gaomon Tablets]

quirks: add a default resolution for Huion devices The Inspiroy 2S H641P in default mode (without hid-uclogic support) says the pen interface has a Logical Maximum of 32767. Over the 160x100mm active surface this is ca 205x328 units/mm. This isn't correct across all devices but let's use it as fallback value so the tablets work out of the box. It's hard to set these tablets via 60-evdev.hwdb otherwise because most Huion tablets share a few PIDs only. Note: this doesn't overwrite the kernel resolution it merely provides a fallback where no kernel resolution is set. The firmware report descriptor does set a physical range (2048) but it sets it in cubic inch which is ignored by the kernel: # 0x65, 0x33, // Unit (EnglishLinear: in³) 48 Part-of: <https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1004> 2024-05-23 15:17:24 +10:00			`# Do not edit this file, it will be overwritten on update`
