I am thinking about fixing it just like how 13e7accb81d6 ("genirq: Get rid of GENERIC_MSI_IRQ_DOMAIN") is fixing drivers/dma/qcom/hidma.c - In ufs-qcom.c, use CONFIG_GENERIC_MSI_IRQ instead of CONFIG_GENERIC_MSI_IRQ_DOMAIN, and meanwhile add #ifdef check before calling platform_msi_domain_free_irqs(). Please let me know your idea. Thanks. Regards, Can Guo
