From 6bee1af9dcaa05c2b9289ec26ed121039dfea251 Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Thu, 25 May 2017 15:15:10 -0700 Subject: [PATCH] platform/x86: intel_pmc_ipc: Mark ipc_data_readb() as __maybe_unused The function is currently not used, however it is part of the API and might be used in the future. Adding the attribute fixes the following warning when building with clang: drivers/platform/x86/intel_pmc_ipc.c:189:18: error: unused function 'ipc_data_readb' [-Werror,-Wunused-function] Signed-off-by: Matthias Kaehlcke Signed-off-by: Andy Shevchenko --- drivers/platform/x86/intel_pmc_ipc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/platform/x86/intel_pmc_ipc.c b/drivers/platform/x86/intel_pmc_ipc.c index e4d4dfe3e1d1..bb792a52248b 100644 --- a/drivers/platform/x86/intel_pmc_ipc.c +++ b/drivers/platform/x86/intel_pmc_ipc.c @@ -186,7 +186,7 @@ static inline void ipc_data_writel(u32 data, u32 offset) writel(data, ipcdev.ipc_base + IPC_WRITE_BUFFER + offset); } -static inline u8 ipc_data_readb(u32 offset) +static inline u8 __maybe_unused ipc_data_readb(u32 offset) { return readb(ipcdev.ipc_base + IPC_READ_BUFFER + offset); } -- 2.20.1
