From: Arnd Bergmann Date: Mon, 9 May 2016 19:47:23 +0000 (+0200) Subject: netfilter: conntrack: remove uninitialized shadow variable X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c047c3b1af6214b447e353527e394fa3f3e86397;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git netfilter: conntrack: remove uninitialized shadow variable A recent commit introduced an unconditional use of an uninitialized variable, as reported in this gcc warning: net/netfilter/nf_conntrack_core.c: In function '__nf_conntrack_confirm': net/netfilter/nf_conntrack_core.c:632:33: error: 'ctinfo' may be used uninitialized in this function [-Werror=maybe-uninitialized] bytes = atomic64_read(&counter[CTINFO2DIR(ctinfo)].bytes); ^ net/netfilter/nf_conntrack_core.c:628:26: note: 'ctinfo' was declared here enum ip_conntrack_info ctinfo; The problem is that a local variable shadows the function parameter. This removes the local variable, which looks like what Pablo originally intended.
