Subject: efi: Small leak on error in runtime map code
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=86d68a58d00db3770735b5919ef2c6b12d7f06f3;p=deliverable%2Flinux.git

efi: Small leak on error in runtime map code

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

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