Introduce the function ata_dev_free_resources() to free the resources
allocated to support a device features. For now, this function is
reduced to calling zpodd_exit() for devices that have this feature
enabled.
ata_dev_free_resources() is called from ata_eh_dev_disable() as this
function is always called for all devices attached to a port that is
being detached and for devices that are being disabled due to being
removed (detached) from the system or due to errors.
With this change, the call to zpodd_exit() done in ata_port_detach()
and ata_scsi_handle_link_detach() are removed as these functions
remove all devices attached to the link or port using libata EH, thus
resulting in ata_eh_dev_disable() being called and the zpodd_exit()
function being executed.

The 512B buffer sector_buf field of struct ata_port is used for scanning
devices as well as during error recovery with ata EH. This buffer is
thus useless if a port does not have a device connected to it.
And also given that commands using this buffer are issued to devices,
and not to ports, move this buffer definition from struct ata_port to
struct ata_device.
This change slightly increases system memory usage for systems using a
port-multiplier as in that case we do not need a per-device buffer for
scanning devices (PMP does not allow parallel scanning) nor for EH (as
when entering EH we are guaranteed that all commands to all devices
connected to the PMP have completed or have been aborted). However,
this change reduces memory usage on systems that have many ports with
only few devices rives connected, which is a much more common use case
than the PMP use case.

The function ata_eh_read_sense_success_ncq_log() does more that just
reading the sense data for successful NCQ commands log page as it also
sets the sense data for all commands listed in the log page.
Rename this function to ata_eh_get_ncq_success_sense() to better
describe what the function does. Furthermore, since this function is
only called from ata_eh_get_success_sense() in libata-eh.c, there is no
need to export it and its declaration can be moved to
drivers/ata/libata.h.
To be consistent with this change, the function
ata_eh_read_sense_success_non_ncq() is also renamed to
ata_eh_get_non_ncq_success_sense().

Unlike ata_std_prereset() and ata_std_postreset(), the function
sata_std_hardreset() applies only to SATA devices, as its name implies.
So move its definition to libata-sata.c.
Together with this, also move the definition of sata_port_ops to
libata-sata.c, where it belongs.

The function __ata_qc_complete() is always called with a qc that already
has been dereferenced and so is guaranteed to be non-NULL (as otherwise
the kernel would have crashed). So remove the warning for a NULL qc as
it is useless.
Furthermore, the qc passed to __ata_qc_complete() must always be marked
as active with the ATA_QCFLAG_ACTIVE flag. If that is not the case, in
addition to the existing warning, return early so that we do not attempt
to complete an invalid qc.
Finally, fix the comment related to clearing the qc active flag as that
operation applies to all devices, not just ATAPI ones.

A struct ata_device flags should always be set and cleared with the
device port locked. Testing for a flag should thus also be done while
holding the device port lock. In accordance to this principle, modify

flag while holding the device port lock.

Move the ATA link transport device related functions after the ATA
transport device related functions to avoid the need for forward
declaring ata_tdev_add() and ata_tdev_delete().
And while at it, do the following:
1) Change ata_is_ata_dev() and ata_is_link() to return a boolean
2) Fix a pointer declaration style in ata_is_ata_dev()
3) Improve the kdoc comments for ata_tdev_free(), ata_tdev_delete(),

The macro LIST_HEAD() declares a list variable and
initializes it, which can be used to simplify the steps
of list initialization, thereby simplifying the code.
These serials just do some equivalatent substitutions,
and with no functional modifications.

Merge series from Andre Przywara <andre.przywara@arm.com>:
This is remainder of the AXP717 fix series, containing support for the
boost regulator. This is meant to increase the battery voltage to the 5
volts required to provide the USB VBUS power.
It's the usual trinity of DT bindings patch (1/3), the MFD part
describing the PMIC registers (2/3) and the final patch to model the
regulator (3/3).
Compared to v2, this drops the merged patches, and just retains the
boost related parts. It also changes the internal name of the register
to AXP717_MODULE_EN_CONTROL_2, since there is another control register
we will need later for battery support.

clang warns on this because it has an unannotated fall-through between
cases:
arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.
gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break. Odd.

If a queue is being destroyed but causes a HWS hang on removal, the KFD
may issue an unnecessary gpu reset if the destroyed queue can be fixed
by a queue reset.
This is because the queue has been removed from the KFD's queue list
prior to the preemption action on destroy so the reset call will fail to
match the HQD PQ reset information against the KFD's queue record to do
the actual reset.
To fix this, deactivate the queue prior to preemption since it's being
destroyed anyways and remove the queue from the KFD's queue list after
preemption.

Function used to check the number of FEs connected to the current BE.
This was then used to determine if the symclk could be disabled, if
all FEs were disconnected. However, the function would skip over the
primary FE and return 0 when the primary FE was still connected. This
caused black screens on driver disable with an MST daisy chain hooked
up.

Refactor the function to correctly return the number of FEs connected
to the input BE. Also, rename it for clarity.

dc_state_destruct() nulls the resource context of the DC state. The pipe
context passed to dcn35_set_drr() is a member of this resource context.
If dc_state_destruct() is called parallel to the IRQ processing (which
calls dcn35_set_drr() at some point), we can end up using already nulled
function callback fields of struct stream_resource.
The logic in dcn35_set_drr() already tries to avoid this, by checking tg
against NULL. But if the nulling happens exactly after the NULL check and
before the next access, then we get a race.
Avoid this by copying tg first to a local variable, and then use this
variable for all the operations. This should work, as long as nobody
frees the resource pool where the timing generators live.

dpp401_dscl_program_isharp
This commit addresses a missing kdoc for the 'bs_coeffs_updated'
parameter in the 'dpp401_dscl_program_isharp' function. The
'bs_coeffs_updated' is a flag indicating whether the Blur and Scale
Coefficients have been updated.
The 'dpp401_dscl_program_isharp' function is responsible for programming
the isharp, which includes setting the isharp filter, noise gain, and
blur and scale coefficients. If the 'bs_coeffs_updated' flag is set to
true, the function updates the blur and scale coefficients.
Fixes the below with gcc W=1:
drivers/gpu/drm/amd/amdgpu/../display/dc/dpp/dcn401/dcn401_dpp_dscl.c:961: warning: Function parameter or struct member 'bs_coeffs_updated' not described in 'dpp401_dscl_program_isharp'

Rework how VM operations synchronize to submissions. Provide an
amdgpu_sync container to the backends instead of an reservation
object and fill in the amdgpu_sync object in the higher layers
of the code.
No intended functional change, just prepares for upcomming changes.
