Subject: [PATCH] optionrom: Turn off -fcf-protection
Date: Mon, 3 Jan 2022 10:01:12 +0100 [thread overview]
Message-ID: <20220103090112.312202-1-bjorn@kernel.org> (raw)
Ubuntu GCC enables -fcf-protection globally, which is not supported
for x86 16-bit (realmode). This causes the build to fail.
This commit turns off that option.
