Subject: [PATCH wireless-next 17/28] wifi: iwlwifi: mld: use warn-on-once in error path.
Date: Wed, 11 Mar 2026 16:07:19 -0700 [thread overview]
Message-ID: <20260311230730.163348-18-greearb@candelatech.com> (raw)
In-Reply-To: <20260311230730.163348-1-greearb@candelatech.com>
From: Ben Greear <greearb@candelatech.com>
Just splat a WARNING once, and add debug output to indicate
a bit about why it is hitting the warn path.
