From 5f4d55d5791a8b7150dbaba239e92719ae0f94d4 Mon Sep 17 00:00:00 2001 From: Lior Cohen Date: Wed, 29 May 2019 16:39:55 +0300 Subject: [PATCH] iwlwifi: mvm: change TLC config cmd sent by rs to be async The TLC_MNG_CONFIG sync cmd sent by the rs leads to a kernel warning of sleeping while in rcu read-side critical section. The fix is to change the command to be ASYNC (not blocking for the response anymore).
