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.

Sometimes local functions are called indirectly from the hw driver, which only makes the code harder to follow. Remove these. Method .hw_init is only called from platform driver probe, which is not relevant, so don't set this either.

Vaibhav Gupta authored
Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings.

The driver calls pci_enable_wake(...., false) in pmcraid_resume(), and there is no corresponding pci_enable_wake(...., true) in pmcraid_suspend(). Either it should do enable-wake the device in .suspend() or should not invoke pci_enable_wake() at all.

Both runtime_suspend_v3_hw() and runtime_resume_v3_hw() do nothing else but invoke suspend_v3_hw() and resume_v3_hw() respectively. This is the case of unnecessary function calls. To use those functions for runtime pm as well, simply use UNIVERSAL_DEV_PM_OPS. make -j$(nproc) W=1, with CONFIG_PM disabled, throws '-Wunused-function' warning for runtime_suspend_v3_hw() and runtime_resume_v3_hw(). After dropping those function definitions, the warning was thrown for suspend_v3_hw() and resume_v3_hw(). Hence, mark them as '__maybe_unused'.
