Subject: [PATCH v2 07/30] misc: vmw_vmci_defs: Mark 'struct vmci_handle VMCI_ANON_SRC_HANDLE' as __maybe_unused
Date: Wed, 1 Jul 2020 09:30:55 +0100 [thread overview]
Message-ID: <20200701083118.45744-8-lee.jones@linaro.org> (raw)
In-Reply-To: <20200701083118.45744-1-lee.jones@linaro.org>
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 = {
