From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mathieu Malaterre Date: Thu, 22 Mar 2018 20:20:05 +0000 Subject: [PATCH 19/19] powerpc/tau: Synchronize function prototypes and body Message-Id: <20180322202007.23088-20-malat@debian.org> List-Id: References: <20180322202007.23088-1-malat@debian.org> In-Reply-To: <20180322202007.23088-1-malat@debian.org> MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit To: Michael Ellerman Cc: Mathieu Malaterre , Benjamin Herrenschmidt , Paul Mackerras , linuxppc-dev@lists.ozlabs.org, linux-kernel@vger.kernel.org, kvm-ppc@vger.kernel.org Some function prototypes and body for Thermal Assist Units were not in sync. Update the function definition to match the existing function declaration found in `setup-common.c`, changing an `int` return type to a `u32` return type. Move the prototypes to a header file. Fix the following warnings, treated as error with W=1: arch/powerpc/kernel/tau_6xx.c:257:5: error: no previous prototype for ‘cpu_temp_both’ [-Werror=missing-prototypes] arch/powerpc/kernel/tau_6xx.c:262:5: error: no previous prototype for ‘cpu_temp’ [-Werror=missing-prototypes] arch/powerpc/kernel/tau_6xx.c:267:5: error: no previous prototype for ‘tau_interrupts’ [-Werror=missing-prototypes] Compile tested with CONFIG_TAU_INT.
