From 9c8f55798a9d716daed4de6d7038a21c3ca6e673 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 21 Aug 2015 09:29:50 -0700 Subject: [PATCH] Input: sentelic - silence some underflow warnings I have a static checker that complains when we check for an upper bound but don't have a corresponding check for a lower bound. With this code, the upper bound check seems not really required, so it is not a bug to leave the lower bound check out as well. But let's silence the warning by making these variables unsigned.
