Subject: [PATCH] xwayland: avoid race condition on new keymap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the Wayland compositor notifies of a new keymap, for the first X11
client using the keyboard, the last slave keyboard used might still not
be set (i.e. “lastSlave” is still NULL).

As a result, the new keymap is not applied, and the first X11 window
will have the wrong keymap set initially.

Apply the new keymap to the master keyboard as long as there's one.
