Subject: [PATCH 1/2] [v2] crypto: hisilicon - avoid unused function warning
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.
Fixes: 79e09f30eeba ("crypto: hisilicon - add SRIOV support for ZIP")
