Peter Anvin" , linux-kernel@vger.kernel.org, Noah Burchell Subject: [PATCH] x86/reboot: Remove dead code after machine_real_restart() Message-ID: <20261102062417.56725-1-noah@nburch.org> Feedback-ID: 224137974:user:proton X-Pm-Message-ID: d8a8bafd5913ab97b5ce4426b9baa8b47ab753bc X-Mailing-List: linux-kernel@vger.kernel.org List-Id: List-Post: List-Help: List-Subscribe: List-Unsubscribe: List-Owner: Precedence: list MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable machine_real_restart() is __noreturn and ends in unreachable(), so the reboot_type assignment and the break after it in the BOOT_BIOS case can never execute. Remove them. No functional change.
