| |
4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Parav Pandit <parav@mellanox.com>
commit 921c0f5ba58e4064deb18b4985a202508fc5527f upstream.
It is incorrect to depend on set_id value to know if counters were allocated or not. set_id_valid field is set to true when counters were allocated. Therefore, use set_id_valid while deciding to free counters.
