Subject: [PATCH] csky: Remove compile warning for CONFIG_SMP
Date: Sun, 19 Oct 2025 07:02:14 -0400 [thread overview]
Message-ID: <20251019110214.3392011-1-guoren@kernel.org> (raw)
From: "Guo Ren (Alibaba DAMO Academy)" <guoren@kernel.org>
When CONFIG_SMP is enabled, there is a compile warning:
arch/csky/kernel/smp.c:242:6: warning: no previous prototype for
'csky_start_secondary' [-Wmissing-prototypes]
242 | void csky_start_secondary(void)
| ^~~~~~~~~~~~~~~~~~~~
Add a similar prototype with csky_start in sections.h.
