From 84ecc2f6eb1cb12e6d44818f94fa49b50f06e6ac Mon Sep 17 00:00:00 2001
From: Gen Zhang <blackgod016574@gmail.com>
Date: Thu, 23 May 2019 08:34:52 +0800
Subject: consolemap: Fix a memory leaking bug in drivers/tty/vt/consolemap.c
In function con_insert_unipair(), when allocation for p2 and p1[n]
fails, ENOMEM is returned, but previously allocated p1 is not freed,
remains as leaking memory. Thus we should free p1 as well when this
allocation fails.
