Greg Kroah-Hartman 09b0965ee8 IB: mlx5: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Geert Uytterhoeven 0c40c1be25 mmc: dw_mmc: Fix debugfs on 64-bit platforms
"dw_mci.pending_events" and "dw_mci.completed_events" are "unsigned
long", i.e. 32-bit or 64-bit, depending on the platform.  Hence casting
their addresses to "u32 *", and calling debugfs_create_x32() breaks
operation on 64-bit platforms.

Fix this by using the new debugfs_create_xul() helper instead.

Geert Uytterhoeven d3504757f3 debugfs: Add debugfs_create_xul() for hexadecimal unsigned long
The existing debugfs_create_ulong() function supports objects of
type "unsigned long", which are 32-bit or 64-bit depending on the
platform, in decimal form.  To format objects in hexadecimal, various
debugfs_create_x*() functions exist, but all of them take fixed-size
types.

Add a debugfs helper for "unsigned long" objects in hexadecimal format.
This avoids the need for users to open-code the same, or introduce
bugs when casting the value pointer to "u32 *" or "u64 *" to call
debugfs_create_x{32,64}().

Saravana Kannan 15956dad5c of: property: Skip adding device links to suppliers that aren't devices
Some devices need to be initialized really early and can't wait for
driver core or drivers to be functional.  These devices are typically
initialized without creating a struct device for their device nodes.

If a supplier ends up being one of these devices, skip trying to add
device links to them.

Saravana Kannan 0ff5cc1ec3 of: property: Make sure child dependencies don't block probing of parent
When creating device links to proxy the sync_state() needs of child
dependencies, create SYNC_STATE_ONLY device links so that children
dependencies don't block probing of the parent.

Also, differentiate between missing suppliers of parent device vs
missing suppliers of child devices so that driver core doesn't block
parent device probing when only child supplier dependencies are missing.

Saravana Kannan bcbbcfd572 driver core: Allow a device to wait on optional suppliers
Before this change, if a device is waiting on suppliers, it's assumed
that all those suppliers are needed for the device to probe
successfully. This change allows marking a devices as waiting only on
optional suppliers. This allows a device to wait on suppliers (and link
to them as soon as they are available) without preventing the device
from being probed.

Saravana Kannan 05ef983e0d driver core: Add device link support for SYNC_STATE_ONLY flag
Parent devices might need to create "proxy" device links from themselves
to supplier devices to make sure the supplier devices don't get a
sync_state() before the child consumer devices get a chance to add
device links to the supplier devices.

However, the parent device has no real dependency on the supplier device
and probing, suspend/resume or runtime PM don't need to be affected by
the supplier device.  To capture these cases, create a SYNC_STATE_ONLY
device link flag that only affects sync_state() behavior and doesn't
affect probing, suspend/resume or runtime PM.

Mike Christie cf1b2326b7 nbd: verify socket is supported during setup
nbd requires socket families to support the shutdown method so the nbd
recv workqueue can be woken up from its sock_recvmsg call. If the socket
does not support the callout we will leave recv works running or get hangs
later when the device or module is removed.

This adds a check during socket connection/reconnection to make sure the
socket being passed in supports the needed callout.

Mark Brown 962399bb7f ata: libahci_platform: Fix regulator_get_optional() misuse
This driver is using regulator_get_optional() to handle all the supplies
that it handles, and only ever enables and disables all supplies en masse
without ever doing any other configuration of the device to handle missing
power. These are clear signs that the API is being misused - it should only
be used for supplies that may be physically absent from the system and in
these cases the hardware usually needs different configuration if the
supply is missing. Instead use normal regualtor_get(), if the supply is
not described in DT then the framework will substitute a dummy regulator in
so no special handling is needed by the consumer driver.

In the case of the PHY regulator the handling in the driver is a hack to
deal with integrated PHYs; the supplies are only optional in the sense
that that there's some confusion in the code about where they're bound to.
From a code point of view they function exactly as normal supplies so can
be treated as such. It'd probably be better to model this by instantiating
a PHY object for integrated PHYs.

This was preceded by us timing out everything and shutting down the
sockets for the device.  The problem is we had a request in the queue at
the same time, so we completed the request twice.  This can actually
happen in a lot of cases, we fail to get a ref on our config, we only
have one connection and just error out the command, etc.

Fix this by checking cmd->status in nbd_read_stat.  We only change this
under the cmd->lock, so we are safe to check this here and see if we've
already error'ed this command out, which would indicate that we've
completed it as well.

Josef Bacik de6346ecbc nbd: protect cmd->status with cmd->lock
We already do this for the most part, except in timeout and clear_req.
For the timeout case we take the lock after we grab a ref on the config,
but that isn't really necessary because we're safe to touch the cmd at
this point, so just move the order around.

For the clear_req cause this is initiated by the user, so again is safe.

Linus Torvalds 63cbb3b364 ARM: SoC fixes
A slightly larger set of fixes have accrued in the last two weeks.
 Mostly a collection of the usual smaller fixes:
 
  - Marvell Armada: USB phy setup issues on Turris Mox
 
  - Broadcom: GPIO/pinmux DT mapping corrections for Stingray, MMC bus
  width fix for RPi Zero W, GPIO LED removal for RPI CM3. Also some
  maintainer updates.
 
  - OMAP: Fixlets for display config, interrupt settings for wifi, some
    clock/PM pieces. Also IOMMU regression fix and a ti-sysc no-watchdog
    regression fix.
 
  - i.MX: A few fixes around PM/settings, some devicetree fixlets and
  catching up with config option changes in DRM
 
  - Rockchip: RockRro64 misc DT fixups, Hugsun X99 USB-C, Kevin display
  panel settings
 
 ... and some smaller fixes for Davinci (backlight, McBSP DMA), Allwinner
 (phy regulators, PMU removal on A64, etc).

Jens Axboe 2b2ed9750f io_uring: fix bad inflight accounting for SETUP_IOPOLL|SETUP_SQTHREAD
We currently assume that submissions from the sqthread are successful,
and if IO polling is enabled, we use that value for knowing how many
completions to look for. But if we overflowed the CQ ring or some
requests simply got errored and already completed, they won't be
available for polling.

For the case of IO polling and SQTHREAD usage, look at the pending
poll list. If it ever hits empty then we know that we don't have
anymore pollable requests inflight. For that case, simply reset
the inflight count to zero.

Jens Axboe 498ccd9eda io_uring: used cached copies of sq->dropped and cq->overflow
We currently use the ring values directly, but that can lead to issues
if the application is malicious and changes these values on our behalf.
Created in-kernel cached versions of them, and just overwrite the user
side when we update them. This is similar to how we treat the sq/cq
ring tail/head updates.
