Subject: [PATCH] misc: vmw_vmci_defs: Mark 'struct vmci_handle
VMCI_ANON_SRC_HANDLE' as __maybe_unused
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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:

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 = {
