From: Lee Jones Date: Wed, 8 Jul 2020 12:57:09 +0000 (+0100) Subject: misc: vmw_vmci_defs: Mark 'struct vmci_handle VMCI_ANON_SRC_HANDLE' as __maybe_unused X-Git-Tag: v5.15~3208^2~104 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a9f91cebbeb8ea1355e852cce6d40efbcddbfe2b;p=platform%2Fkernel%2Flinux-starfive.git misc: vmw_vmci_defs: Mark 'struct vmci_handle VMCI_ANON_SRC_HANDLE' as __maybe_unused vmw_vmci_defs.h is included by multiple source files. Some of which do not make use of 'struct vmci_handle VMCI_ANON_SRC_HANDLE' rendering it unused. Ensure the compiler knows that this is in fact intentional by marking it as __maybe_unused. This fixes the following W=1 warnings: In file included from drivers/misc/vmw_vmci/vmci_context.c:8: include/linux/vmw_vmci_defs.h:162:33: warning: ‘VMCI_ANON_SRC_HANDLE’ defined but not used [-Wunused-const-variable=] 162 | static const struct vmci_handle VMCI_ANON_SRC_HANDLE = { | ^~~~~~~~~~~~~~~~~~~~ In file included from drivers/misc/vmw_vmci/vmci_datagram.c:8: include/linux/vmw_vmci_defs.h:162:33: warning: ‘VMCI_ANON_SRC_HANDLE’ defined but not used [-Wunused-const-variable=] 162 | static const struct vmci_handle VMCI_ANON_SRC_HANDLE = { | ^~~~~~~~~~~~~~~~~~~~ Cc: George Zhang Signed-off-by: Lee Jones Acked-by: Arnd Bergmann Link: https://lore.kernel.org/r/20200708125711.3443569-2-lee.jones@linaro.org Signed-off-by: Greg Kroah-Hartman --- diff --git a/include/linux/vmw_vmci_defs.h b/include/linux/vmw_vmci_defs.h index fefb529..be0afe6 100644 --- a/include/linux/vmw_vmci_defs.h +++ b/include/linux/vmw_vmci_defs.h @@ -159,7 +159,7 @@ static inline bool vmci_handle_is_invalid(struct vmci_handle h) */ #define VMCI_ANON_SRC_CONTEXT_ID VMCI_INVALID_ID #define VMCI_ANON_SRC_RESOURCE_ID VMCI_INVALID_ID -static const struct vmci_handle VMCI_ANON_SRC_HANDLE = { +static const struct vmci_handle __maybe_unused VMCI_ANON_SRC_HANDLE = { .context = VMCI_ANON_SRC_CONTEXT_ID, .resource = VMCI_ANON_SRC_RESOURCE_ID };
