[PATCH 3.14 90/96] efi: Small leak on error in runtime map code

From: Greg Kroah-Hartman
Date: Mon Mar 16 2015 - 10:53:12 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 86d68a58d00db3770735b5919ef2c6b12d7f06f3 upstream.

The "> 0" here should ">= 0" so we free map_entries[0].

Fixes: 926172d46038 ('efi: Export EFI runtime memory mapping to sysfs')
