Subject: [PATCH] ubsan: use a big if block in Kconfig
Date: Wed, 29 Jan 2020 12:22:51 +0100 [thread overview]
Message-ID: <20200129112251.11515-1-u.kleine-koenig@pengutronix.de> (raw)
A side effect (which was the motivation for this change) is that the
config item CONFIG_UBSAN_ALIGNMENT doesn't appear in configurations that
have CONFIG_UBSAN disabled.
