From 2c4283ca7cdcc6605859c836fc536fcd83a4525f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 20 Aug 2013 11:57:35 +0300 Subject: [PATCH] staging: comedi: dt282x: dt282x_ai_insn_read() always fails 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.
