0572edbc32 scsi: mvumi: Use generic power management
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.

bd7463cdbe scsi: mvumi: Drop PCI Wakeup calls from .resume
The driver calls pci_enable_wake(...., false) in mvumi_resume(), and there
is no corresponding pci_enable_wake(...., true) in mvumi_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
mvumi_resume().

71c8f15e1d scsi: hisi_sas_v3_hw: Remove extra function calls for runtime pm
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'.

Make the pm8001_printk() macro take an explicit HBA instead of assuming the
existence of an unspecified pm8001_ha argument.

1b5d279328 scsi: pm8001: Neaten debug logging macros and uses
Every PM8001_<FOO>_DBG macro uses an internal call to pm8001_printk.

Convert all uses of:

	PM8001_<FOO>_DBG(hba, pm8001_printk(fmt, ...))
to
	pm8001_dbg(hba, <FOO>, fmt, ...)

so the visual complexity of each macro is reduced.

The repetitive macro definitions are converted to a single pm8001_dbg and
the level is concatenated using PM8001_##level##_LOGGING for the specific
level test.

Done with coccinelle, checkpatch and a little typing of the new macro
definition.

Miscellanea:

 - Coalesce formats

 - Realign arguments

 - Add missing terminating newlines to formats

 - Remove trailing spaces from formats

 - Change defective loop with printk(KERN_INFO... to emit a 16 byte hex
   block to %p16h

03fe6a640a scsi: atari_scsi: Fix race condition between .queuecommand and EH
It is possible that bus_reset_cleanup() or .eh_abort_handler could be
invoked during NCR5380_queuecommand(). If that takes place before the new
command is enqueued and after the ST-DMA "lock" has been acquired, the
ST-DMA "lock" will be released again. This will result in a lost DMA
interrupt and a command timeout. Fix this by excluding EH and interrupt
handlers while the new command is enqueued.

66df79ccbc scsi: ufs: Adjust logic in common ADAPT helper
The introduction of ufshcd_dme_configure_adapt() refactored out duplication
from the Mediatek and Qualcomm drivers.

Both these implementations had the logic of:

    gear_tx == UFS_HS_G4 => PA_INITIAL_ADAPT
    gear_tx != UFS_HS_G4 => PA_NO_ADAPT

but now both implementations pass PA_INITIAL_ADAPT as "adapt_val" and if
gear_tx is not UFS_HS_G4 that is replaced with PA_INITIAL_ADAPT. In other
words, it's PA_INITIAL_ADAPT in both above cases.

The result is that e.g. Qualcomm SM8150 has no longer functional UFS, so
adjust the logic to match the previous implementation.
