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 esas2r_resume(), and there is no corresponding pci_enable_wake(...., true) in esas2r_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 esas2r_resume().

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 Link: https://lore.kernel.org/r/49f36a93af7752b613d03c89a87078243567fd9a.1605914030.git.joe@perches.comReported-by:

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.

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.

Several version 2 MADs and the version 2 vfcFrame structures introduced a new targetWWPN field for better identification of a target over the scsi_id.

The FC iu and response payloads are located at different offsets depending on the ibmvfc_cmd version. This is a result of the version 2 vfcFrame definition adding an extra 64bytes of reserved space to the structure prior to the payloads. Add helper routines to determine the current vfcFrame version and return a pointer to the proper iu or response structure within that ibmvfc_cmd.

Testing the NPIV Login response capabilities is a long winded process of dereferencing the vhost->login_buf->resp.capabilities field, then byte swapping that value to host endian, and performing the bitwise test. Currently we only ever check this in ibmvfc_cancel_all(), but follow-up patches will need to regularly check for targetWWPN and channelization support. Add a helper to simplify checking various VIOS capabilities, namely ibmvfc_check_caps(). Link: https://lore.kernel.org/r/20201118011104.296999-4-tyreld@linux.ibm.comAcked-by:

Introduce a target_wwpn field to several MADs. Its possible that a SCSI ID of a target can change due to some fabric changes. The WWPN of the SCSI target provides a better way to identify the target. Also, add flags for receiving MAD versioning information and advertising client support for targetWWPN with the VIOS. This latter capability flag will be required for future clients capable of requesting multiple hardware queues from the host adapter.

The virtual FC frame command exchanged with the VIOS is used for device reset and command abort TMF as well as normally queued commands. When initializing the ibmvfc_cmd there are several elements of the command that are set the same way regardless of the command type. Deduplicate code by moving these commonally set fields into a initialization helper routine, namely ibmvfc_init_vfc_cmd().
