74b04fae45 mei: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

c56967d674 mei: hdcp: Replace one-element array with flexible-array member
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

Also, make use of the array_size() helper instead of the open-coded
version in memcpy(). These sorts of multiplication factors need to
be wrapped in array_size().

And while there, use the preferred form for passing a size of a struct.
The alternative form where struct name is spelled out hurts readability
and introduces an opportunity for a bug when the pointer variable type is
changed but the corresponding sizeof that is passed as argument is not.

ed86a9877d misc: rtsx: Find L1 PM Substates capability instead of hard-coding
Instead of hard-coding the location of the L1 PM Substates capability based
on the Device ID, search for it in the extended capabilities list.  This
works for any device, as long as it implements the L1 PM Substates
capability correctly, so it doesn't require maintenance as new devices are
added.  No functional change intended.

22bf3251d7 misc: rtsx: Remove rtsx_pci_read/write_config() wrappers
rtsx_pci_read_config_dword() and similar wrappers around the PCI config
accessors add very little value, and they obscure the fact that often we
are accessing standard PCI registers that should be coordinated with the
PCI core.

Remove the wrappers and use the PCI config accessors directly.  No
functional change intended.

Instead of using the driver-specific rtsx_pci_write_config_byte() to update
the PCIe Link Control Register, use pcie_capability_write_word() like the

fadbfc38dd hpilo: Replace one-element array with flexible-array member

having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these

no longer be used[2].

For this particular case, it is important to notice that the cachelines
change from 7 to 6 after the flexible-array conversion:

it can stay 'static'.

e852c2c251 mei: bus: don't clean driver pointer
It's not needed to set driver to NULL in mei_cl_device_remove()
which is bus_type remove() handler as this is done anyway
in __device_release_driver().

Actually this is causing an endless loop in driver_detach()
on ubuntu patched kernel, while removing (rmmod) the mei_hdcp module.
The reason list_empty(&drv->p->klist_devices.k_list) is always not-empty.
as the check is always true in  __device_release_driver()
	if (dev->driver != drv)
		return;

The non upstream patch is causing this behavior, titled:
'vfio -- release device lock before userspace requests'

Nevertheless the fix is correct also for the upstream.

34afa1d657 misc/pch_phub.c: use generic power management
Drivers should not use legacy power management as they have to manage power
states and related operations, for the device, themselves. This driver was
handling them with the help of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(), etc.

With generic PM, all essentials will be handled by the PCI core. Driver
needs to do only device-specific operations.

The driver was also using pci_enable_wake(...,..., 0) to disable wake. Use
device_wakeup_disable() instead. It was also saving device register
configuration using pch_phub_save/restore_reg_conf() which is not
recommended.

fail, as the write gets elided. Instead, force the variable to be
volatile, and make similar changes through-out other tests in an effort
to avoid needing to repeat fixing these kinds of problems. Also includes
pr_err() calls in failure paths so that kernel logs are more clear in
the failure case.

The message should just be dropped as the call will print the failure
message anyway.

85c5cbeba8 cxl: Fix kobject memleak
Currently the error return path from kobject_init_and_add() is not
followed by a call to kobject_put() - which means we are leaking
the kobject.

Fix it by adding a call to kobject_put() in the error path of
kobject_init_and_add().

ce04326edd habanalabs: increase h/w timer when checking idle
In GAUDI the current timer value for the hardware to check if it is
in IDLE state is too low. As a result, there are occasions where the H/W
wrongly reports it is not IDLE. The driver checks that before submitting
work on behalf of the driver during initialization, so a false report might
cause the driver to fail during device initialization.

3292055c85 habanalabs: Correct handling when failing to enqueue CB
The fence release flow is different if the CS was never submitted. In that
case, we don't have an hw_sob object attached that we need to "put". While
if the CS was aborted, we do need to "put" the hw_sob.
