[ Upstream commit fca269f2 ] mbigen_write_msg clears eventid bits of a mbigen register when free a interrupt, because msi_domain_deactivate memset struct msg to zero. Then multiple mbigen pins with zero eventid will report the same interrupt number. The eventid clear call trace: free_irq __free_irq irq_shutdown irq_domain_deactivate_irq __irq_domain_deactivate_irq __irq_domain_deactivate_irq msi_domain_deactivate platform_msi_write_msg mbigen_write_msg Signed-off-by:
