[Spice-devel] [PATCH spice-gtk 4/4] spice-widget: Don't change usbredir/automount settings while redirecting

[Hans de Goede]

The keyboard focus may change while usb-device-manager is in the process of
redirecting a usb-device (as this may show a policykit dialog). Making
autoredir/automount setting changes while this is happening is not a good idea!

Since usb-device-manager already sets keyboard_grab_inhibit when it is
redirecting to allow the policykit dialog to show, we can use that to
inhibit usb-autoredir setting changes.
