Date: Wed, 10 Feb 2021 17:23:48 +0200	[thread overview]
Message-ID: <iwlwifi.20210210172142.dfd423b2b2ef.Icd576dc3e2e7174d3ed9c1c32f48ea0013699e72@changeid> (raw)
In-Reply-To: <20210210152355.419776-1-luca@coelho.fi>

From: Golan Ben Ami <golan.ben.ami@intel.com>

Currently, for all devices and families, failing getting the temp
from the fw is indicated in the log as ERR.
This is too severe for two reasons:
1. The driver has a fall back - and schedules the next temp
read immediately after failing to read temp from the fw.
2. The temp read implementation in the fw is different between
HWs, and on older devices the flow is a-sync and may timeout.

Reducing the print severity from ERR to WARN will allow to
track the issue if it will appear many times, but not frighten users
if it appears once.
