hw_event_sas_phy_up() is used in hardirq/softirq context:
pm8001_interrupt_handler_msix() || pm8001_interrupt_handler_intx() || pm8001_tasklet
=> PM8001_CHIP_DISP->isr() = pm80xx_chip_isr()
=> process_oq() [spin_lock_irqsave(&pm8001_ha->lock,)]
=> process_one_iomb()
=> mpi_hw_event()
=> hw_event_sas_phy_up()
=> msleep(200)
Revert the msleep() back to an mdelay() to avoid sleeping in atomic
context.
