This adds the enable attribute which is used to select if zero PWM duty
means to switch off regulator and PWM or to keep them enabled but
at inactive PWM output level.
Depending on the select enable mode, turn off the regulator and PWM if
the PWM duty is zero, or keep them enabled.
This is especially important for fan using inverted PWM signal polarity.
Having regulator supplied and PWM disabled, some PWM controllers provide
the active, rather than inactive signal.
With this change the shutdown as well as suspend/resume paths require
modifcations as well.

Regular calls to set_pwm don't hold the mutex, but the upcoming
update_enable support needs to call set_pwm with the mutex being held.
So provide the previous behavior in set_pwm (handling the lock), while
adding __set_pwm which assumes the lock being held.

Fix a NULL pointer crash that occurs when we are freeing the socket at the
same time we access it via sysfs.
The problem is that:
1. iscsi_sw_tcp_conn_get_param() and iscsi_sw_tcp_host_get_param() take
the frwd_lock and do sock_hold() then drop the frwd_lock. sock_hold()
does a get on the "struct sock".
2. iscsi_sw_tcp_release_conn() does sockfd_put() which does the last put
on the "struct socket" and that does __sock_release() which sets the
sock->ops to NULL.
3. iscsi_sw_tcp_conn_get_param() and iscsi_sw_tcp_host_get_param() then
call kernel_getpeername() which accesses the NULL sock->ops.
Above we do a get on the "struct sock", but we needed a get on the "struct
socket". Originally, we just held the frwd_lock the entire time but in
commit bcf3a2953d ("scsi: iscsi: iscsi_tcp: Avoid holding spinlock while
calling getpeername()") we switched to refcount based because the network
layer changed and started taking a mutex in that path, so we could no
longer hold the frwd_lock.
Instead of trying to maintain multiple refcounts, this just has us use a
mutex for accessing the socket in the interface code paths.

One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct hpt_iop_request_scsi_command and refactor the rest of the
code, accordingly.
The following pieces of code suggest that the one element of array sg_list
in struct hpt_iop_request_scsi_command is not taken into account when
calculating the total size for both struct hpt_iop_request_scsi_command and
the maximum number of elements sg_list will contain:
1047 req->header.size = cpu_to_le32(
1048 sizeof(struct hpt_iop_request_scsi_command)
1049 - sizeof(struct hpt_iopsg)
1050 + sg_count * sizeof(struct hpt_iopsg));
1400 req_size = sizeof(struct hpt_iop_request_scsi_command) 1401 + sizeof(struct hpt_iopsg) * (hba->max_sg_descriptors - 1);
So it's safe to replace the one-element array with a flexible-array member
and update the code above, accordingly: now we don't need to subtract
sizeof(struct hpt_iopsg) from sizeof(struct hpt_iop_request_scsi_command)
because this is implicitly done by the flex-array transformation.

The issue is that the per-device running_req read in
pm8001_dev_gone_notify() never goes to zero and we never make progress.
This is caused by missing accounting for running_req for when an internal
abort command completes.
In commit 2cbbf48977 ("scsi: pm8001: Use libsas internal abort support")
we started to send internal abort commands as a proper sas_task. In this
when we deliver a sas_task to HW the per-device running_req is incremented
in pm8001_queue_command(). However it is never decremented for internal
abort commnds, so decrement in pm8001_mpi_task_abort_resp().

When executing SMP task failed, the smp_execute_task_sg() calls del_timer()
to delete "slow_task->timer". However, if the timer handler
sas_task_internal_timedout() is running, the del_timer() in

is shown below:
(thread 1) | (thread 2)

the timer handler have finished before the "task->slow_task" is
deallocated.

"Regression and bug fixes:
- Performance regression fix from 5.18 on a Rasberry Pi
- Fix extent parsing bug which triggers a BUG_ON when a (corrupted)
extent tree has has a non-root node when zero entries.
- Fix a livelock where in the right (wrong) circumstances a large
number of nfsd threads can try to write to a nearly full file
system, and retry for hours(!)"

ext4: use buckets for cr 1 block scan instead of rbtree
ext4: use locality group preallocation for small closed files
ext4: make directory inode spreading reflect flexbg size
ext4: avoid unnecessary spreading of allocations among groups
ext4: make mballoc try target group first even with mb_optimize_scan

ASUSTeK COMPUTER INC. ROG Flow X13 has a problem with fans upon wakeup from
s2idle. In examining the ASL, functions 3 and 4 are not called in the AMD
codepath but only in the Microsoft codepath.
Add the system to the quirk list to force Microsoft codepath.

Lenovo Slim 7 Pro 14ARH7 has a sporadically non-functional keyboard
when resuming from s2idle. This is caused by some missing calls to the
EC that don't occur in the AMD codepath but only in the Microsoft codepath.
Add the system to the quirk list to force Microsoft codepath.

ASUS TUF Gaming A17 FA707RE has problems with ACPI events after
s2idle resume. It's from a missing call to an ASL method in AMD
the s2idle calling path. Force the system to use the Microsoft
Modern Standby calling path instead.

OEMs have made some mistakes in the past for the AMD GUID support
and not populated the method properly. To add an escape hatch for
this problem introduce a module parameter that can force using
the Microsoft GUID.
This is intentionally introduced to both Intel and AMD codepaths
to allow using the parameter as a debugging tactic on either.

A mistake was made that only AMDI0007 was set to rev of "2", but
it should have been also set for AMDI008. If an ID is missing from
the _HID table, then assume it matches Rembrandt behavior.
This implicitly means that if any other behavior changes happen
in the future missing IDs must be added to that table.
