From 6d20e6b235aad0be463b23588093b079362bb2e4 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 25 Aug 2017 13:19:58 +0300 Subject: [PATCH] um: return negative in tuntap_open_tramp() The intention is to return negative error codes. "pid" is already negative but we accidentally negate it again back to positive.
