    Subject[PATCH 1/3] misc: vmw_vmci_defs: Mark 'struct vmci_handle VMCI_ANON_SRC_HANDLE' as __maybe_unused
    Date
    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 = {
    | ^~~~~~~~~~~~~~~~~~~~
