Subject: debugfs: convert gid= argument from decimal, not octal
X-Git-Tag: v3.8~140^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f1688e0431d3a395388e70fe21da89ed0de0c323;p=platform%2Fkernel%2Flinux-amlogic.git

debugfs: convert gid= argument from decimal, not octal

This patch technically breaks userspace, but I suspect that anyone who
actually used this flag would have encountered this brokenness, declared
it lunacy, and already sent a patch.
