From d07a74a546981a09ba490936645fbf0d1340b96c Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Thu, 25 Aug 2011 16:13:55 -0700 Subject: dmaengine: fix missing 'cnt' in ?: in dmatest Hi, On the latest tree my compiler has started giving the warning: drivers/dma/dmatest.c:575:28: warning: the omitted middle operand in ?: will always be ?true?, suggest explicit middle operand [-Wparentheses] The following patch fixes the missing middle clause with the same fix that Nicolas Ferre used in the similar clauses. (There seems to have been a race between him fixing that and the extra clause going in a little later). I don't actually know the dmatest code/structures, nor do I own any hardware to test it on (assuming it needs a DMA engine); but this patch builds, the existing code is almost certainly wrong and the fix is the same as the corresponding lines above it. (WTH is x=y?:z legal C anyway?)
