Subject: [PATCH 06/14] wifi: iwlwifi: dbg-tlv: use struct_size() for allocation
Date: Sun, 28 Jan 2024 08:53:52 +0200 [thread overview]
Message-ID: <20240128084842.f301641eb916.I66b7b48a526377d682eecef874373bf3a01076c8@changeid> (raw)
In-Reply-To: <20240128065400.2550604-1-miriam.rachel.korenblit@intel.com>
From: Johannes Berg <johannes.berg@intel.com>
This is effectively the same since we don't even have a
multiplication, but better captures what happens with
the length.
