| Subject: staging: comedi: dt282x: dt282x_ai_insn_read() always fails |
| |
| 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. |
