b5ba32b63c ata: pata_mpc52xx: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() is renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

f810b81ce8 ata: sata_sx4: drop already completed TODO
The TODO claims that the pdc_20621_ops should set the .inherits
function pointer to &ata_base_port_ops after it has been converted
to use the new EH.

However, the driver was converted to use the new EH a long time ago,
in commit 67651ee571 ("[libata] sata_sx4: convert to new exception
handling methods"), which also did set .inherits function pointer to
&ata_sff_port_ops (and ata_sff_port_ops itself has .inherits set to
&ata_base_port_ops).

541528170a ata,scsi: remove ata_sas_port_init()
ata_sas_port_init() now only contains a single initialization.

Move this single initialization to ata_sas_port_alloc(), since:
1) ata_sas_port_alloc() already initializes some of the struct members.
2) ata_sas_port_alloc() is only used by libsas.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

0a368a5c4e Merge branch 'selftests-mlxsw'
Petr Machata says:

====================
selftests: New selftests for out-of-order-operations patches in mlxsw

In the past, the mlxsw driver made the assumption that the user applies
configuration in a bottom-up manner. Thus netdevices needed to be added to
the bridge before IP addresses were configured on that bridge or SVI added
on top of it, because whatever happened before a netdevice was mlxsw upper
was generally ignored by mlxsw. Recently, several patch series were pushed
to introduce the bookkeeping and replays necessary to offload the full
state, not just the immediate configuration step.

In this patchset, introduce new selftests that directly exercise the out of
order code paths in mlxsw.

- Patch #1 adds new tests into the existing selftest router_bridge.sh.
- Patches #2-#5 add new generic selftests.
- Patches #6-#8 add new mlxsw-specific selftests.

eb1388553e selftests: router_bridge: Add remastering tests
Add two tests to deslave a port from and reenslave to a bridge. This should
retain the ability of the system to forward traffic, but on an offloading
driver that is sensitive to ordering of operations, it might not.

The first test does this configuration in a way that relies on
vlan_default_pvid to assign the PVID. The second test disables that
autoconfiguration and configures PVID by hand in a separate step.

8e4bb53c90 drm/bridge: Add debugfs print for bridge chains
DRM bridges are not visible to the userspace and it may not be
immediately clear if the chain is somehow constructed incorrectly. I
have had two separate instances of a bridge driver failing to do a
drm_bridge_attach() call, resulting in the bridge connector not being
part of the chain. In some situations this doesn't seem to cause issues,
but it will if DRM_BRIDGE_ATTACH_NO_CONNECTOR flag is used.

Add a debugfs file to print the bridge chains. For me, on this TI AM62
based platform, I get the following output:

encoder[39]
	bridge[0] type: 0, ops: 0x0
	bridge[1] type: 0, ops: 0x0, OF: /bus@f0000/i2c@20000000/dsi@e:toshiba,tc358778
	bridge[2] type: 0, ops: 0x3, OF: /bus@f0000/i2c@20010000/hdmi@48:lontium,lt8912b
	bridge[3] type: 11, ops: 0x7, OF: /hdmi-connector:hdmi-connector

0a85890559 ata,scsi: do not issue START STOP UNIT on resume
During system resume, ata_port_pm_resume() triggers ata EH to
1) Resume the controller
2) Reset and rescan the ports
3) Revalidate devices
This EH execution is started asynchronously from ata_port_pm_resume(),
which means that when sd_resume() is executed, none or only part of the
above processing may have been executed. However, sd_resume() issues a
START STOP UNIT to wake up the drive from sleep mode. This command is
translated to ATA with ata_scsi_start_stop_xlat() and issued to the
device. However, depending on the state of execution of the EH process
and revalidation triggerred by ata_port_pm_resume(), two things may
happen:
1) The START STOP UNIT fails if it is received before the controller has
   been reenabled at the beginning of the EH execution. This is visible
   with error messages like:

ata10.00: device reported invalid CHS sector 0
sd 9:0:0:0: [sdc] Start/Stop Unit failed: Result: hostbyte=DID_OK driverbyte=DRIVER_OK
sd 9:0:0:0: [sdc] Sense Key : Illegal Request [current]
sd 9:0:0:0: [sdc] Add. Sense: Unaligned write command
sd 9:0:0:0: PM: dpm_run_callback(): scsi_bus_resume+0x0/0x90 returns -5
sd 9:0:0:0: PM: failed to resume async: error -5

2) The START STOP UNIT command is received while the EH process is
   on-going, which mean that it is stopped and must wait for its
   completion, at which point the command is rather useless as the drive
   is already fully spun up already. This case results also in a
   significant delay in sd_resume() which is observable by users as
   the entire system resume completion is delayed.

Given that ATA devices will be woken up by libata activity on resume,
sd_resume() has no need to issue a START STOP UNIT command, which solves
the above mentioned problems. Do not issue this command by introducing
the new scsi_device flag no_start_on_resume and setting this flag to 1
in ata_scsi_dev_config(). sd_resume() is modified to issue a START STOP
UNIT command only if this flag is not set.
