Subject: [PATCH 02/34] ubsan: fix unused variable warning in test module
Date: Wed,  3 Apr 2024 10:06:20 +0200	[thread overview]
Message-ID: <20240403080702.3509288-3-arnd@kernel.org> (raw)
In-Reply-To: <20240403080702.3509288-1-arnd@kernel.org>

From: Arnd Bergmann <arnd@arndb.de>

This is one of the drivers with an unused variable that is marked 'const'.
Adding a __used annotation here avoids the warning and lets us enable
the option by default:

lib/test_ubsan.c:137:28: error: unused variable 'skip_ubsan_array' [-Werror,-Wunused-const-variable]

Fixes: 4a26f49b7b3d ("ubsan: expand tests and reporting")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
