Subject: evdev: A joystick could be ignored before opening input device
X-Git-Tag: accepted/tizen/unified/20250205.095548~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dcfd1e4667d0031ddaeb06135d16dde8e2e15b9f;p=platform%2Fupstream%2Flibinput.git

evdev: A joystick could be ignored before opening input device

add checking if the builtin property 'ID_INPUT_JOYSTICK' is set.
Because 'LIBINPUT_IGNORE_DEVICE' is usually set by udev rule,
it may not be determined until the udev rule is parsed.

A joystick is not supported in libinput for now.
