c37baa06f8 ARM: OMAP2+: Fix undefined reference to omap_secure_init
omap_secure_init() is now called from all OMAP2+ platforms during their
init_early() call. This function is in omap-secure.o so include that
in the build for these platforms.

207270dd0b gpiolib: hold gpio devices lock until ->descs array is initialised
If a driver consuming the GPIO chip is being probed at the same time as
the GPIO driver is registering the chip, it is possible for the
consuming driver to see the ->descs array in an uninitialised state.
For example, the gpio-keys-polled driver can fail like this:

    kernel: gpiod_request: invalid GPIO (no device)
    kernel: gpio-keys-polled PRP0001:07: failed to get gpio: -22
    kernel: gpio-keys-polled: probe of PRP0001:07 failed with error -22

This patch makes gpiochip_add() hold the lock protecting gpio_devices
until it has finished setting desc->gdev on the newly inserted list
entry.

06e26b75f5 pinctrl: mvebu: armada-37xx: use use platform api
platform_irq_count() and platform_get_irq() is the more generic
way (independent of device trees) to determine the count of available
interrupts. So use this instead.

As platform_irq_count() might return an error code (which
of_irq_count doesn't) some additional handling is necessary.

d5331ec2cc gpio: mvebu: clear irq in edge cause register before unmask edge irq
When input GPIO set from 0 to 1, the interrupt bit asserted in the GPIO
Interrupt Cause Register (ICR) even if the corresponding interrupt
masked in the GPIO Interrupt Mask Register.

Because interrupt mask register only affects assertion of the interrupt
bits in Main Interrupt Cause Register and it does not affect the
setting of bits in the GPIO ICR.

So, there is problem, when we unmask interrupt with already
asserted bit in the GPIO ICR, then false interrupt immediately occurs
even if GPIO don't change their value since last unmask.

366950eeb6 gpiolib: Lower verbosity when allocating hierarchy irq
In the current codes, the following 3 lines would be output to
the console for each irq line.
  gpio gpiochip0: (gpio_thunderx): allocate IRQ 10, hwirq 0
  gpio gpiochip0: (gpio_thunderx): found parent hwirq 245784
  gpio gpiochip0: (gpio_thunderx): alloc_irqs_parent for 10 parent hwirq 245784

In general, there are about tens of irq lines for each gpio chip,
and then it would emit so many insignificant log in the boot process.
These infos are more suitable for the dbg purpose. So change these
to the dbg level. With this change, about 200 lines are suppressed
on my Marvell cn96xx board.

5b3014b952 IMA: Defined delayed workqueue to free the queued keys
Keys queued for measurement should be freed if a custom IMA policy
was not loaded.  Otherwise, the keys will remain queued forever
consuming kernel memory.

This patch defines a delayed workqueue to handle the above scenario.
The workqueue handler is setup to execute 5 minutes after IMA
initialization is completed.

If a custom IMA policy is loaded before the workqueue handler is
scheduled to execute, the workqueue task is cancelled and any queued keys
are processed for measurement.  But if a custom policy was not loaded then
the queued keys are just freed when the delayed workqueue handler is run.

450d0fd515 IMA: Call workqueue functions to measure queued keys
Measuring keys requires a custom IMA policy to be loaded.  Keys should
be queued for measurement if a custom IMA policy is not yet loaded.
Keys queued for measurement, if any, should be processed when a custom
policy is loaded.

This patch updates the IMA hook function ima_post_key_create_or_update()
to queue the key if a custom IMA policy has not yet been loaded.  And,
ima_update_policy() function, which is called when a custom IMA policy
is loaded, is updated to process queued keys.

This patch defines a workqueue for queuing keys when a custom IMA policy

IMA_QUEUE_EARLY_BOOT_KEYS is used to declare the workqueue functions.

A flag namely ima_process_keys is used to check if the key should be
queued or should be processed immediately.

Looking into the output from usbmon, the interesting part is the
following data packet:

  ffff880069c63e00 30710169 C Ci:1:002:0 0 143 = 09028f00 01030080
  00090403 00000e01 00000924 03000103 7c003328 010204db

If we drop the lead configuration and interface descriptors, we're left
with an output terminal descriptor describing a generic display:

  /* Output terminal descriptor */
  buf[0]	09
  buf[1]	24
  buf[2]	03	/* UVC_VC_OUTPUT_TERMINAL */
  buf[3]	00	/* ID */
  buf[4]	01	/* type == 0x0301 (UVC_OTT_DISPLAY) */
  buf[5]	03
  buf[6]	7c
  buf[7]	00	/* source ID refers to self! */
  buf[8]	33

The problem with this descriptor is that it is self-referential: the
source ID of 0 matches itself! This causes the 'struct uvc_entity'
representing the display to be added to its chain list twice during
'uvc_scan_chain()': once via 'uvc_scan_chain_entity()' when it is
processed directly from the 'dev->entities' list and then again
immediately afterwards when trying to follow the source ID in
'uvc_scan_chain_forward()'

Add a check before adding an entity to a chain list to ensure that the
entity is not already part of a chain.

ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization order
The code which checks the return value for snd_soc_add_dai_link() call
in soc_tplg_fe_link_create() moved the snd_soc_add_dai_link() call before
link->dobj members initialization.

While it does not affect the latest kernels, the old soc-core.c code
in the stable kernels is affected. The snd_soc_add_dai_link() function uses
the link->dobj.type member to check, if the link structure is valid.

Reorder the link->dobj initialization to make things work again.
It's harmless for the recent code (and the structure should be properly
initialized before other calls anyway).

The problem is in stable linux-5.4.y since version 5.4.11 when the
upstream commit 76d2703649 was applied.
