Subject: [PATCH v2 08/47] iwlwifi: mvm: Init error table memory to zero
Date: Wed, 9 Dec 2020 23:16:12 +0200 [thread overview]
Message-ID: <iwlwifi.20201209231352.742786ffddba.Id7a17985f5bf6a03d3850f445ccdc611f97776ce@changeid> (raw)
In-Reply-To: <20201209211651.968276-1-luca@coelho.fi>
From: Mordechay Goodstein <mordechay.goodstein@intel.com>
If case we have an error reading FW memory we get garbage (stack old
data) in the report, so just initialize the table to zero.
