2020-11-25scsi: arcmsr: Use generic power managementVaibhav Gupta
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.

2020-11-25scsi: arcmsr: Drop PCI wakeup calls from .resumeVaibhav Gupta
The driver calls pci_enable_wake(...., false) in arcmsr_resume(), and there is no corresponding pci_enable_wake(...., true) in arcmsr_suspend(). Either it should do enable-wake the device in .suspend() or should not invoke pci_enable_wake() at all. Concluding that this driver doesn't support enable-wake and PCI core calls pci_enable_wake(pci_dev, PCI_D0, false) during resume, drop it from arcmsr_resume().

The end result is that (IMHO), it is now a lot easier to read it as a text file, while producing a good html output.

2018-01-22scsi: arcmsr: avoid do_gettimeofdayArnd Bergmann
The arcmsr uses its own implementation of time_to_tm(), along with do_gettimeofday() to read the current time. While the algorithm used here is fine in principle, it suffers from two problems: - it assigns the seconds portion of the timeval to a 32-bit unsigned integer that overflows in 2106 even on 64-bit architectures. - do_gettimeofday() returns a time_t that overflows in 2038 on all 32-bit systems. This changes the time retrieval function to ktime_get_real_seconds(), which returns a proper 64-bit value, and replaces the open-coded time_to_tm() algorithm with a call to the safe time64_to_tm(). I checked way all numbers are indexed and found that months are given in range 0..11 while the days are in range 1..31, same as 'struct tm', but the year value that the firmware expects starts in 2000 while 'struct tm' is based on year 1900, so it needs a small adjustment.
