Wysocki" Cc: Arnd Bergmann , Len Brown , nvdimm@lists.linux.dev, linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org Subject: [PATCH 1/3] acpi: nfit: add declaration in a local header Date: Tue, 16 May 2023 22:14:07 +0200 Message-Id: <20230516201415.556858-1-arnd@kernel.org> X-Mailer: git-send-email 2.39.2 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-acpi@vger.kernel.org From: Arnd Bergmann The nfit_intel_shutdown_status() function has a __weak defintion in nfit.c and an override in acpi_nfit_test.c for testing purposes. This works without an extern declaration, but causes a W=1 build warning: drivers/acpi/nfit/core.c:1717:13: error: no previous prototype for 'nfit_intel_shutdown_status' [-Werror=missing-prototypes] Add a declaration in a header that gets included from both sides to shut up the warning and ensure that the prototypes actually match.
