commit f6bcb4c7f366905b66ce8ffca7190118244bb642 upstream.
This code will leak "map->debugfs_name" because the if statement is
reversed so it only frees NULL pointers instead of non-NULL. In
fact the if statement is not required and should just be removed
because kfree() accepts NULL pointers.Fixes: cffa4b2122f5 ("regmap: debugfs: Fix a memory leak when calling regmap_attach_dev")

commit 47f4469970d8861bc06d2d4d45ac8200ff07c693 upstream.
While commit d5dcce0c414f ("device property: Keep secondary firmware
node secondary by type") describes everything correct in its commit
message, the change it made does the opposite and original commit
c15e1bdda436 ("device property: Fix the secondary firmware node handling
in set_primary_fwnode()") was fully correct.Revert the former one here and improve documentation in the next patch.

commit 66482f640755b31cb94371ff6cef17400cda6db5 upstream.
The device_links_purge() function (called from device_del()) tries to
remove the links.needs_suppliers list entry, but it's using
list_del(), hence it doesn't initialize after the removal. This is OK
for normal cases where device_del() is called via device_destroy().
However, it's not guaranteed that the device object will be really
deleted soon after device_del(). In a minor case like HD-audio codec
reconfiguration that re-initializes the device after device_del(), it
may lead to a crash by the corrupted list entry.As a simple fix, replace list_del() with list_del_init() in order to
make the list intact after the device_del() call.Fixes: e2ae9bcc4aaa ("driver core: Add support for linking devices during device addition")

This reverts commit 9b947a13e7f6017f18470f665992dbae267852b3.
The commit 9b947a13e7f6017f18470f665992dbae267852b3 does not consider power and
clock when expose the regmap into debugsfs. This may bring some problem for some
case. E.g., For reset registers (not real GPR, but csi bridge register) for
MIPI DSI, MIPI CSI and LCDIF on i.mx8mm, they only can be accessed after the
disp_root clock and dispmix power has been turned on, otherwise the system may
be stuck.on i.mx8mm evk, the command to reproduce (with default dtb, no display/capture
running):
cat /sys/kernel/debug/regmap/dummy-display-gpr@32e28000/registersThis patch reverted previous commit to avoid the exposure.

For a domain has no working devices anymore, let's choose the deepest state
to enter to save power. e.g. driver probe failure.Signed-off-by: Dong Aisheng
-
Currently the generic power domain will power off the domain if all
devices in it have been stopped during system suspend.It is done by checking if the domain is active in genpd_sync_power_off,
then disable it. However, for power domains supporting multiple low power
states, it may have already entered an intermediate low power state by
runtime PM before system suspend and the status is already
GPD_STATE_POWER_OFF which results in then the power domain stay at an
intermediate low power state during system suspend.
Then genpd_sync_power_off will keep it at the low power state instead
of completely gate off it.Let's give the power domain a chance to switch to the deepest state in
case it's already off but in an intermediate low power state.Signed-off-by: Dong Aisheng

Move the Subdomain check into _genpd_power_off, then the caller does
not have to check it each time. This also ensures a double check
of &genpd->sd_count before really power off domain in case it's
increased asychronously by subdomains. This is the same behavior
as the original genpd_power_off() does.Signed-off-by: Dong Aisheng

Only moving device pm to tail for defer probe is not enough because

Since the device is resumed from runtime-suspend in
__device_release_driver() anyway, it is better to do that before
looking for busy managed device links from it to consumers, because
if there are any, device_links_unbind_consumers() will be called
and it will cause the consumer devices' drivers to unbind, so the
consumer devices will be runtime-resumed. In turn, resuming each
consumer device will cause the supplier to be resumed and when the
runtime PM references from the given consumer to it are dropped, it
may be suspended. Then, the runtime-resume of the next consumer
will cause the supplier to resume again and so on.Update the code accordingly.

After commit d12544fb2aa9 ("PM: runtime: Remove link state checks in

runtime PM from acquiring additional references to the supplier
device after pm_runtime_clean_up_links() has run (or even while it
is running), so calling this function from __device_release_driver()
may be pointless (or even harmful).Moreover, it ignores stateless device links, so the runtime PM
handling of managed and stateless device links is inconsistent
because of it, so better get rid of it entirely.Fixes: d12544fb2aa9 ("PM: runtime: Remove link state checks in rpm_get/put_supplier()")

It appears that firmware nodes can be shared between devices. In such case
when a (child) device is about to be deleted, its firmware node may be shared
and ACPI_COMPANION_SET(..., NULL) call for it breaks the secondary link
of the shared primary firmware node.In order to prevent that, check, if the device has a parent and parent's
firmware node is shared with its child, and avoid crashing the link.Fixes: c15e1bdda436 ("device property: Fix the secondary firmware node handling in set_primary_fwnode()")

Behind primary and secondary we understand the type of the nodes
which might define their ordering. However, if primary node gone,
we can't maintain the ordering by definition of the linked list.
Thus, by ordering secondary node becomes first in the list.
But in this case the meaning of it is still secondary (or auxiliary).
The type of the node is maintained by the secondary pointer in it:secondary pointer Meaning
NULL or valid primary node
ERR_PTR(-ENODEV) secondary nodeSo, if by some reason we do the following sequence of calls
set_primary_fwnode(dev, NULL);
set_primary_fwnode(dev, primary);we should preserve secondary node.
This concept is supported by the description of set_primary_fwnode()
along with implementation of set_secondary_fwnode(). Hence, fix
the commit c15e1bdda436 to follow this as well.Fixes: c15e1bdda436 ("device property: Fix the secondary firmware node handling in set_primary_fwnode()")

At boot time, or when doing memory hot-add operations, if the links in
sysfs can't be created, the system is still able to run, so just report
the error in the kernel log rather than BUG_ON and potentially make system
unusable because the callpath can be called with locks held.Since the number of memory blocks managed could be high, the messages are
rate limited.As a consequence, link_mem_sections() has no status to report anymore.

A device may have specific HW constraints that must be obeyed to, before
its corresponding PM domain (genpd) can be powered off - and vice verse at
power on. These constraints can't be managed through the regular runtime PM
based deployment for a device, because the access pattern for it, isn't
always request based. In other words, using the runtime PM callbacks to
deal with the constraints doesn't work for these cases.For these reasons, let's instead add a PM domain power on/off notification
mechanism to genpd. To add/remove a notifier for a device, the device must
already have been attached to the genpd, which also means that it needs to
be a part of the PM domain topology.To add/remove a notifier, let's introduce two genpd specific functions:
- dev_pm_genpd_add|remove_notifier()Note that, to further clarify when genpd power on/off notifiers may be
used, one can compare with the existing CPU_CLUSTER_PM_ENTER|EXIT
notifiers. In the long run, the genpd power on/off notifiers should be able
to replace them, but that requires additional genpd based platform support
for the current users.Signed-off-by: Ulf Hansson
