Subject: [PATCH 02/10][next] scsi: aacraid: Use struct_size() helper in aac_get_safw_ciss_luns()
Date: Wed, 28 Jun 2023 11:54:58 -0600 [thread overview]
Message-ID: <cd80ea8f2446fe62ec15ffb0bbcecb69e0c342af.1687974498.git.gustavoars@kernel.org> (raw)
In-Reply-To: <cover.1687974498.git.gustavoars@kernel.org>
Prefer struct_size() over open-coded versions.
This results in no differences in binary output.
