Subject: [PATCH v3 02/19] thunderbolt: Remove __packed from ICM message structures
Date: Mon, 2 Oct 2017 13:38:29 +0300 [thread overview]
Message-ID: <20171002103846.64602-3-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20171002103846.64602-1-mika.westerberg@linux.intel.com>
These messages are all 32-byte aligned and they should be packed without
the __packed attribute just fine. It also allows compiler to generate
better code on some architectures.
