Subject: [PATCH] riscv: Mark default_power_off() as __noreturn
Date: Mon, 27 Jul 2026 12:03:39 +0200 [thread overview]
Message-ID: <20260727100339.410466-2-thorsten.blum@linux.dev> (raw)
Since default_power_off() never returns, annotate it with the __noreturn
attribute to improve compiler optimizations.
