Subject: seat: Add ds_seat_set_keyboard()
X-Git-Tag: accepted/tizen/unified/20220718.140337~13
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F07%2F278107%2F1;p=platform%2Fcore%2Fuifw%2Flibds.git

seat: Add ds_seat_set_keyboard()

The ds_seat_set_keyboard() enables a seat to refer to a ds_keyboard, so
that the seat reads keymap and repeat info from ds_keyboard and then
sends them to the wayland clients.
