From c0d3e166e16ac8f12fc005e620671671f4d2ae0f Mon Sep 17 00:00:00 2001 From: Yufen Yu Date: Thu, 16 May 2019 19:30:07 -0700 Subject: nvme: fix memory leak for power latency tolerance [ Upstream commit 510a405d945bc985abc513fafe45890cac34fafa ] Unconditionally hide device pm latency tolerance when uninitializing the controller to ensure all qos resources are released so that we're not leaking this memory. This is safe to call if none were allocated in the first place, or were previously freed.
