I think this should be changed to
- if (mux->idle_state == mux->cached_state)
+ if (mux->idle_state == mux->cached_state ||
+ mux->idle_state == MUX_IDLE_AS_IS)
continue;
or the following mux_control_set will be called with state ==
MUX_IDLE_AS_IS. Alternatively, mux_control_set should return when passed
this value.
