staging: comedi: dt282x: dt282x_ai_insn_read() always fails
commit 2c4283ca7cdcc6605859c836fc536fcd83a4525f upstream.
In dt282x_ai_insn_read() we call this macro like:
wait_for(!mux_busy(), comedi_error(dev, "timeout\n"); return -ETIME;);
Because the if statement doesn't have curly braces it means we always
return -ETIME and the function never succeeds.
