Subject: [PATCH v2 1/3] powerpc: ps3: move udbg_shutdown_ps3gelic prototype
Date: Thu, 23 Nov 2023 11:47:59 +0100 [thread overview]
Message-ID: <20231123104801.15537-2-arnd@kernel.org> (raw)
In-Reply-To: <20231123104801.15537-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
Allmodconfig kernels produce a missing-prototypes warning:
arch/powerpc/platforms/ps3/gelic_udbg.c:239:6: error: no previous prototype for 'udbg_shutdown_ps3gelic' [-Werror=missing-prototypes]
Move the declaration from a local header to asm/ps3.h where it can be
seen from both the caller and the definition. As suggested
by Michael Ellerman, remove the CONFIG_PS3GELIC_UDBG option to
prevent this from causing a build regression.
