Subject: powercap/dtpm: Fixup kfree for virtual node
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=690de0b4013f6f35bc9fced12746b9f396c471ae;p=linux.git

powercap/dtpm: Fixup kfree for virtual node

When the node is virtual there is no release function associated which
can free the memory.

Free the memory when no 'ops' exists.
