3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@oracle.com>
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.
