VF drivers can only use GuC-based TLB invalidation, as they don't
have access to the related registers. However, VFs shouldn't need
any explicit TLB invalidation before enabling CTB communication,
as there will be an implicit GGTT TLB invalidation issued by the
GuC itself as part of MMIO-based action handling.

There are no RTP save-restore actions applicable for VFs on
current platforms. If any future platform will require some,
we will need to update the RTP framework to support VF_READY
or VF_ONLY actions. In the meantime, just skip all actions if
we are running as VF driver.

In the aspeed UDC setup, we configure the UDC hardware with the assigned
USB device address.
However, we have an off-by-one in the bitmask, so we're only setting the
lower 6 bits of the address (USB addresses being 7 bits, and the
hardware bitmask being bits 0:6).
This means that device enumeration fails if the assigned address is
greater than 64:
[ 344.607255] usb 1-1: new high-speed USB device number 63 using ehci-platform
[ 344.808459] usb 1-1: New USB device found, idVendor=cc00, idProduct=cc00, bcdDevice= 6.10

Use the correct mask of 0x7f (rather than 0x3f), and generate this
through the GENMASK macro, so we have numbers that correspond exactly
to the hardware register definition.

avoid deadlock
When config CONFIG_USB_DWC3_DUAL_ROLE is selected, and trigger system
to enter suspend status with below command:
echo mem > /sys/power/state
There will be a deadlock issue occurring. Detailed invoking path as
below:
dwc3_suspend_common()
spin_lock_irqsave(&dwc->lock, flags); <-- 1st
dwc3_gadget_suspend(dwc);
dwc3_gadget_soft_disconnect(dwc);
spin_lock_irqsave(&dwc->lock, flags); <-- 2nd
This issue is exposed by commit c7ebd8149ee5 ("usb: dwc3: gadget: Fix
NULL pointer dereference in dwc3_gadget_suspend") that removes the code
of checking whether dwc->gadget_driver is NULL or not. It causes the
following code is executed and deadlock occurs when trying to get the
spinlock. In fact, the root cause is the commit 5265397f9442("usb: dwc3:
Remove DWC3 locking during gadget suspend/resume") that forgot to remove
the lock of otg mode. So, remove the redundant lock of otg mode during
gadget suspend/resume.

The device_for_each_child_node() macro requires explicit calls to
fwnode_handle_put() in all early exits of the loop if the child node is
not required outside. Otherwise, the child node's refcount is not
decremented and the resource is not released.
The current implementation of pmic_glink_ucsi_probe() makes use of the
device_for_each_child_node(), but does not release the child node on
early returns. Add the missing calls to fwnode_handle_put().

Some LG Gram laptops report a bogus connector change event after a
GET_PDOS command for the partner's source PDOs, which disappears from
the CCI after acknowledging the command. However, the subsequent
GET_CONNECTOR_STATUS in ucsi_handle_connector_change() still reports
this bogus change in bits 5 and 6, leading to the UCSI core re-checking
the partner's source PDOs and thus to an infinite loop.
Fix this by adding a quirk that signals when a potentially buggy GET_PDOS
command is used, checks the status change report and clears it if it is a
bogus event before sending it to the UCSI core.

Sometimes errors are seen, when doing DR swap, like:
[ 24.672481] ucsi-stm32g0-i2c 0-0035: UCSI_GET_PDOS failed (-5)
[ 24.720188] ucsi-stm32g0-i2c 0-0035: ucsi_handle_connector_change:
GET_CONNECTOR_STATUS failed (-5)
There may be some race, which lead to read CCI, before the command complete
flag is set, hence returning -EIO. Similar fix has been done also in
ucsi_acpi [1].
In case of a spurious or otherwise delayed notification it is
possible that CCI still reports the previous completion. The
UCSI spec is aware of this and provides two completion bits in
CCI, one for normal commands and one for acks. As acks and commands
alternate the notification handler can determine if the completion
bit is from the current command.
To fix this add the ACK_PENDING bit for ucsi_stm32g0 and only complete
commands if the completion bit matches.

Syzbot is still reporting quite an old issue [1] that occurs due to
incomplete checking of present usb endpoints. As such, wrong
endpoints types may be used at urb sumbitting stage which in turn
triggers a warning in usb_submit_urb().
Fix the issue by verifying that required endpoint types are present
for both in and out endpoints, taking into account cmd endpoint type.
Unfortunately, this patch has not been tested on real hardware.

printer_read() and printer_write() guard against the race
against disable() by checking the dev->interface flag,
which in turn is guarded by a spinlock.
These functions, however, drop the lock on multiple occasions.
This means that the test has to be redone after reacquiring
the lock and before doing IO.
Add the tests.

The OA ioctl's already have drm_dbg's which are sufficient to tell the user
that OA is not supported on unsupported configurations (execlist mode and
platform gen < 12). Having additional WARN_ON's for these during driver
probe create unnecessary noise. Just remove these WARN_ON's.

When UMD ask config to be updated, xe_oa_config_locked() was calling
xe_oa_emit_oa_config() that would use stream->oa_config but that is
only changed to the next oa_config after xe_oa_emit_oa_config() finish.
So it was setting the same config for all DRM_XE_PERF_IOCTL_CONFIG
calls.

As the driver supports more devices over time the single MODULE_ALIAS
is complete and raises several warnings:
SPI driver ads7846 has no spi_device_id for ti,tsc2046
SPI driver ads7846 has no spi_device_id for ti,ads7843
SPI driver ads7846 has no spi_device_id for ti,ads7845
SPI driver ads7846 has no spi_device_id for ti,ads7873
Fix this by adding a spi_device_id table and removing the manual
MODULE_ALIAS.

priv->pdev pointer was set after being used in
fsl_asoc_card_audmux_init().
Move this assignment at the start of the probe function, so
sub-functions can correctly use pdev through priv.
fsl_asoc_card_audmux_init() dereferences priv->pdev to get access to the
dev struct, used with dev_err macros.
As priv is zero-initialised, there would be a NULL pointer dereference.
Note that if priv->dev is dereferenced before assignment but never used,
for example if there is no error to be printed, the driver won't crash
probably due to compiler optimisations.

sdhci_check_ro() can call mmc_gpio_get_ro() while holding the sdhci
host->lock spinlock. That would be a problem if the GPIO access done by
mmc_gpio_get_ro() needed to sleep.
However, host->lock is not needed anyway. The mmc core ensures that host
operations do not race with each other, and asynchronous callbacks like the
interrupt handler, software timeouts, completion work etc, cannot affect
sdhci_check_ro().
So remove the locking.

mmc_of_parse() reads device property "wp-inverted" and sets
MMC_CAP2_RO_ACTIVE_HIGH if it is true. MMC_CAP2_RO_ACTIVE_HIGH is used
to invert a write-protect (AKA read-only) GPIO value.
sdhci_get_property() also reads "wp-inverted" and sets
SDHCI_QUIRK_INVERTED_WRITE_PROTECT which is used to invert the
write-protect value as well but also acts upon a value read out from the
SDHCI_PRESENT_STATE register.
Many drivers call both mmc_of_parse() and sdhci_get_property(),
so that both MMC_CAP2_RO_ACTIVE_HIGH and
SDHCI_QUIRK_INVERTED_WRITE_PROTECT will be set if the controller has
device property "wp-inverted".
Amend the logic in sdhci_check_ro() to allow for that possibility,
so that the write-protect value is not inverted twice.
Also do not invert the value if it is a negative error value. Note that
callers treat an error the same as not-write-protected, so the result is
functionally the same in that case.
Also do not invert the value if sdhci host operation ->get_ro() is used.
None of the users of that callback set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
directly or indirectly, but two do call mmc_gpio_get_ro(), so leave it to
them to deal with that if they ever set SDHCI_QUIRK_INVERTED_WRITE_PROTECT
in the future.

The formula of Coverage alpha blending is:
dst.a = dst.a * (0xff - src.a * SCA / 0xff) / 0xff
+ src.a * SCA / 0xff
dst.a: destination alpha
src.a: pixel alpha
SCA : plane alpha
When SCA = 0xff, the formula becomes:
dst.a = dst.a * (0xff - src.a) + src.a
This patch is to set the destination alpha (background) to 0xff:
- When dst.a = 0 (before), dst.a = src.a
- When dst.a = 0xff (after) , dst.a = 0xff * (0xff - src.a) + src.a
According to the fomula above:
- When src.a = 0 , dst.a = 0
- When src.a = 0xff, dst.a = 0xff
This two cases are just still correct. But when src.a is
between 0 and 0xff, the difference starts to appear
