Subject: [PATCH 08/14] wifi: iwlwifi: fw: dbg: ensure correct config name sizes
Date: Sun, 28 Jan 2024 08:53:54 +0200 [thread overview]
Message-ID: <20240128084842.58fcdea2ace7.I49cb1d7bdbea12085aada0c96ef42fcbcb3d2b38@changeid> (raw)
In-Reply-To: <20240128065400.2550604-1-miriam.rachel.korenblit@intel.com>
From: Johannes Berg <johannes.berg@intel.com>
This hard-codes the size, but it's not obvious why that's
correct. Use sizeof() and cross-check the two structs.
