From 54f3f994e9964466855e11068c0f7d952d58b260 Mon Sep 17 00:00:00 2001 From: Shahar S Matityahu Date: Mon, 20 Aug 2018 17:16:21 +0300 Subject: iwlwifi: fix D3 debug data buffer memory leak If the driver is unloaded when D3 debug data pulling is enabled but not triggered, it doesn't release the data buffer. Fix this by adding iwl_fw_runtime_free and calling it from the relevant places.
