Subject: [PATCH] arm64/fpsimd: hide unused sve_to_fpsimd() function
Date: Sat, 3 May 2025 16:05:10 +0200 [thread overview]
Message-ID: <20250503140514.487947-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The one caller outside of an #ifdef was removed:
arch/arm64/kernel/fpsimd.c:676:13: error: 'sve_to_fpsimd' defined but not used [-Werror=unused-function]
676 | static void sve_to_fpsimd(struct task_struct *task)
| ^~~~~~~~~~~~~
Add annother #ifdef around the definition.
Fixes: 929fa99b1215 ("arm64/fpsimd: signal: Always save+flush state early")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
