The only caller of hisi_zip_vf_q_assign() is hidden in an #ifdef, so the function causes a warning when CONFIG_PCI_IOV is disabled: drivers/crypto/hisilicon/zip/zip_main.c:740:12: error: unused function 'hisi_zip_vf_q_assign' [-Werror,-Wunused-function] Replace the #ifdef with an IS_ENABLED() check that leads to the function being dropped based on the configuration.
