Pull driver core updates from Greg KH:
"Here is the big set of driver core patches for 5.15-rc1.
These do change a number of different things across different
subsystems, and because of that, there were 2 stable tags created that
might have already come into your tree from different pulls that did
the following
- changed the bus remove callback to return void
- sysfs iomem_get_mapping rework
Other than those two things, there's only a few small things in here:
- kernfs performance improvements for huge numbers of sysfs users at
once
- tiny api cleanups
- other minor changes
All of these have been in linux-next for a while with no reported
problems, other than the before-mentioned merge issue"

Oltean <vladimir.oltean@nxp.com>:
The ls-extirq irqchip driver accesses regmap inside its implementation
of the struct irq_chip :: irq_set_type method, and currently regmap
only knows to lock using normal spinlocks. But the method above wants
raw spinlock context, so this isn't going to work and triggers a
"[ BUG: Invalid wait context ]" splat.
The best we can do given the arrangement of the code is to patch regmap
and the syscon driver: regmap to support raw spinlocks, and syscon to
request them on behalf of its ls-extirq consumer.

Some drivers might access regmap in a context where a raw spinlock is
held. An example is drivers/irqchip/irq-ls-extirq.c, which calls
regmap_update_bits() from struct irq_chip :: irq_set_type, which is a
method called by __irq_set_trigger() under the desc->lock raw spin lock.
Since desc->lock is a raw spin lock and the regmap internal lock for
mmio is a plain spinlock (which can become sleepable on RT), this is an
invalid locking scheme and we get a splat stating that this is a
"[ BUG: Invalid wait context ]".
It seems reasonable for regmap to have an option use a raw spinlock too,
so add that in the config such that drivers can request it.

GENPD core doesn't support handling performance state changes while
consumer device is runtime-suspended or when runtime PM is disabled.
GENPD core may override performance state that was configured by device
driver while RPM of the device was disabled or device was RPM-suspended.
Let's close that gap by allowing drivers to control performance state
while RPM of a consumer device is disabled and to set up performance
state of RPM-suspended device that will be applied by GENPD core on
RPM-resume of the device.

Some devices within power domains with performance states do not
support DVFS, but still need to vote on a default/static state
while they are active. They can express this using the 'required-opps'
property in device tree, which points to the phandle of the OPP
supported by the corresponding power-domains.
Add support to parse this information from DT and then set the
specified performance state during attach and drop it on detach.
runtime suspend/resume callbacks already have logic to drop/set
the vote as needed and should take care of dropping the default
perf state vote on runtime suspend and restore it back on runtime
resume.

fwnode->secondary"
This reverts commit acd418bfcfc415cf5e6414b6d1c6acfec850f290. Checking for
endpoints against fwnode->secondary in fwnode_graph_get_next_endpoint() is
a better way to do this since that function is also used in a bunch of
other places, for instance sensor drivers checking that they do have an
endpoint connected during probe.
This reversion depends on the previous patch in this series, "device property:
Check fwnode->secondary in fwnode_graph_get_next_endpoint()".

Sensor drivers often check for an endpoint to make sure that they're
connected to a consuming device like a CIO2 during .probe(). Some of
those endpoints might be in the form of software_nodes assigned as
a secondary to the device's fwnode_handle. Account for this possibility
in fwnode_graph_get_next_endpoint() to avoid having to do it in the
sensor drivers themselves.

However, the size of this file is limited to PAGE_SIZE because of the

Multi-MSI uses a single MSI descriptor and there is a single mask register
when the device supports per vector masking. To avoid reading back the mask
register the value is cached in the MSI descriptor and updates are done by
clearing and setting bits in the cache and writing it to the device.
But nothing protects msi_desc::masked and the mask register from being
modified concurrently on two different CPUs for two different Linux
interrupts which belong to the same multi-MSI descriptor.
Add a lock to struct device and protect any operation on the mask and the
mask register with it.
This makes the update of msi_desc::masked unconditional, but there is no
place which requires a modification of the hardware register without
updating the masked cache.
msi_mask_irq() is now an empty wrapper which will be cleaned up in follow
up changes.
The problem goes way back to the initial support of multi-MSI, but picking
the commit which introduced the mask cache is a valid cut off point
(2.6.30).

Managed device links are deleted by device_del(). However it is possible to
add a device link to a consumer before device_add(), and then discovering
an error prevents the device from being used. In that case normally
references to the device would be dropped and the device would be deleted.
However the device link holds a reference to the device, so the device link
and device remain indefinitely (unless the supplier is deleted).
For UFSHCD, if a LUN fails to probe (e.g. absent BOOT WLUN), the device
will not have been registered but can still have a device link holding a
reference to the device. The unwanted device link will prevent runtime
suspend indefinitely.
Amend device link removal to accept removal of a link with an unregistered
consumer device (suggested by Rafael), and fix UFSHCD by explicitly
deleting the device link when SCSI destroys the SCSI device.

The reg_fields array fed to {devm_}regmap_field_bulk_alloc is currently
not const, which is not correct on semantics (the functions shouldn't
change reg_field contents) and prevents pre-defined const reg_field
array to be used.
As the implementation of this function doesn't change the content of it,
just add const to its prototype.

This use-after-free happens when a fw_priv object has been freed but
hasn't been removed from the pending list (pending_fw_head). The next
time fw_load_sysfs_fallback tries to insert into the list, it ends up
accessing the pending_list member of the previously freed fw_priv.
The root cause here is that all code paths that abort the fw load
don't delete it from the pending list. For example:
_request_firmware()
-> fw_abort_batch_reqs()
-> fw_state_aborted()
To fix this, delete the fw_priv from the list in __fw_set_state() if
the new state is DONE or ABORTED. This way, all aborts will remove
the fw_priv from the list. Accordingly, remove calls to list_del_init
that were being made before calling fw_state_(aborted|done).
Also, in fw_load_sysfs_fallback, don't add the fw_priv to the pending
list if it is already aborted. Instead, just jump out and return early.

The only motivation for using -EAGAIN in commit 0542ad88fbdd81bb
("firmware loader: Fix _request_firmware_load() return val for fw load
abort") was to distinguish the error from -ENOMEM, and so there is no
real reason in keeping it. -EAGAIN is typically used to tell the
userspace to try something again and in this case re-using the sysfs
loading interface cannot be retried when a timeout happens, so the
return value is also bogus.
-ETIMEDOUT is received when the wait times out and returning that
is much more telling of what the reason for the failure was. So, just
propagate that instead of returning -EAGAIN.

This issue is introduced by commit d0243bbd5dd3 ("drivers core:

dma_range_map before the call to devres_release_all, which is too
early. The solution is to free dma_range_map only after

Since commit 69031f500865 ("swiotlb: Set dev->dma_io_tlb_mem to the
swiotlb pool used"), 'struct device' may hold a copy of the global
'io_default_tlb_mem' pointer if the device is using swiotlb for DMA. A
subsequent call to swiotlb_exit() will therefore leave dangling pointers
behind in these device structures, resulting in KASAN splats such as:
| BUG: KASAN: use-after-free in __iommu_dma_unmap_swiotlb+0x64/0xb0

Convert 'io_default_tlb_mem' to a static structure, so that the
per-device pointers remain valid after swiotlb_exit() has been invoked.
All users are updated to reference the static structure directly, using
the 'nslabs' field to determine whether swiotlb has been initialised.
The 'slots' array is still allocated dynamically and referenced via a
pointer rather than a flexible array member.

This race was discovered when I carefully analyzed the code to locate
another firmware-related UAF issue. It can be triggered only when the
firmware load operation is executed during suspend. This possibility is
almost impossible because there are few firmware load and suspend actions
in the actual environment.
CPU0 CPU1
__device_uncache_fw_images(): assign_fw():
fw_cache_piggyback_on_request()
<----- P0
spin_lock(&fwc->name_lock);
...
list_del(&fce->list);
spin_unlock(&fwc->name_lock);
uncache_firmware(fce->name);
<----- P1
kref_get(&fw_priv->ref);
If CPU1 is interrupted at position P0, the new 'fce' has been added to the
list fwc->fw_names by the fw_cache_piggyback_on_request(). In this case,
CPU0 executes __device_uncache_fw_images() and will be able to see it when
it traverses list fwc->fw_names. Before CPU1 executes kref_get() at P1, if
CPU0 further executes uncache_firmware(), the count of fw_priv->ref may
decrease to 0, causing fw_priv to be released in advance.
Move kref_get() to the lock protection range of fwc->name_lock to fix it.

The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.
This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.
With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

While for most kinds of issues we have counters, tracepoints, or metrics
with a stable interface which can reliably be used to indicate issues,
in order to react to production issues quickly we sometimes need to work
with the interface which most kernel developers naturally use when
developing: printk, and printk-esques like dev_printk.
dev_printk is by far the most likely custom subsystem printk to benefit
from the printk indexing infrastructure, since niche device issues
brought about by production changes, firmware upgrades, and the like are
one of the most common things that we need printk infrastructure's
assistance to monitor.
Often these errors were never expected to practically manifest in
reality, and exhibit in code without extensive (or any) metrics present.
As such, there are typically very few options for issue detection
available to those with large fleets at the time the incident happens,
and we thus benefit strongly from monitoring netconsole in these
instances.
As such, add the infrastructure for dev_printk to be indexed in the
printk index. Even on a minimal kernel config, the coverage of the base
kernel's printk index is significantly improved:
Before:
[root@ktst ~]# wc -l /sys/kernel/debug/printk/index/vmlinux
4497 /sys/kernel/debug/printk/index/vmlinux
After:
[root@ktst ~]# wc -l /sys/kernel/debug/printk/index/vmlinux
5573 /sys/kernel/debug/printk/index/vmlinux
In terms of implementation, in order to trivially disambiguate them,
dev_printk is now a macro which wraps _dev_printk.
