From 78f0a64f66d4f582987bbe45433374b61c21500f Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Wed, 12 May 2021 00:15:49 +0300 Subject: [PATCH] brcmfmac: Silence error messages about unsupported firmware features KMSG is flooded with error messages about unsupported firmware features of BCM4329 chip. The GET_ASSOCLIST error became especially noisy with a newer NetworkManager version of Ubuntu 21.04. Turn the noisy error messages into info messages and print them out only once.
