Subject: [PATCH] gcc-9: silence 'address-of-packed-member' warning
Date: Thu, 12 Sep 2019 08:54:39 +0200 [thread overview]
Message-ID: <20190912065439.2816-1-s.hauer@pengutronix.de> (raw)
As done in the Linux Kernel. Most of the packed structures we have
are optimized to not generate any unaligned accesses, so this warning
produces a lot of false positives which are hard to fix in the code.
