stable inclusion from stable-v6.6.33 commit f0b4617d80c35ce60a3d9d5ead9f97f4058bc7b6 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2

--------------------------------
[ Upstream commit 01acaf3aa75e1641442cc23d8fe0a7bb4226efb1 ]
vmpic_msi_feature is only used conditionally, which triggers a rare -Werror=unused-const-variable= warning with gcc:
arch/powerpc/sysdev/fsl_msi.c:567:37: error: 'vmpic_msi_feature' defined but not used [-Werror=unused-const-variable=] 567 | static const struct fsl_msi_feature vmpic_msi_feature =
Hide this one in the same #ifdef as the reference so we can turn on the warning by default.
