Various macros were used to access raw_cmd for R/W or format commands
without making it obvious that raw_cmd->cmd[] was used. Let's expand

dm timer ops set_load() api allows to configure the load value and to
set the auto reload feature. But auto reload feature is independent of
load value and should be part of configuring pwm. This way pwm can be
disabled by disabling auto reload feature using set_pwm() so that the
current pwm cycle will be completed. Else pwm disabling causes the
cycle to be stopped abruptly.

omap_dm_timer_ops provide support to configure the pwm but there is no
support to get the current status. For configuring pwm it is advised to
check the current hw status instead of relying on pwm framework. So
implement a new timer ops to get the current status of pwm.

Write to trigger register(OMAP_TIMER_TRIGGER_REG) will load the value
in Load register(OMAP_TIMER_LOAD_REG) into Counter register
(OMAP_TIMER_COUNTER_REG).
omap_dm_timer_set_load() writes into trigger register every time load
register is updated. When timer is configured in pwm mode, this causes
disruption in current pwm cycle, which is not expected especially when
pwm is used as PPS signal for synchronized PTP clocks. So do not write
into trigger register on updating the period.

and restore
omap_dm_timer_enable() restores the entire context(including counter)
based on 2 conditions:
- If get_context_loss_count is populated and context is lost.
- If get_context_loss_count is not populated update unconditionally.
Case2 has a side effect of updating the counter register even though
context is not lost. When timer is configured in pwm mode, this is
causing undesired behaviour in the pwm period.
Instead of using get_context_loss_count call back, implement cpu_pm
notifier with context save and restore support. And delete the
get_context_loss_count callback all together.

The virmidi driver handles sysex event exceptionally in a short-cut
snd_seq_dump_var_event() call, but this missed the reset of the
running status. As a result, it may lead to an incomplete command
right after the sysex when an event with the same running status was
queued.
Fix it by clearing the running status properly via alling
snd_midi_event_reset_decode() for that code path.

ethtool: fail with error if request has unknown flags
Jakub Kicinski pointed out that if unrecognized flags are set in netlink
header request, kernel shoud fail with an error rather than silently
ignore them so that we have more freedom in future flags semantics.
To help userspace with handling such errors, inform the client which
flags are supported by kernel. For that purpose, we need to allow
passing cookies as part of extack also in case of error (they can be
only passed on success now).

As pointed out by Jakub Kicinski, we ethtool netlink code should respond
with an error if request head has flags set which are not recognized by
kernel, either as a mistake or because it expects functionality introduced
in later kernel versions.
To avoid unnecessary roundtrips, use extack cookie to provide the
information about supported request flags.

Commit ba0dc5f6e0ba ("netlink: allow sending extended ACK with cookie on

extended ack message in the form of NLMSGERR_ATTR_COOKIE attribute.
Currently the cookie is ignored if error code is non-zero but there is
no technical reason for such limitation and it can be useful to provide
machine parseable information as part of an error message.
Include NLMSGERR_ATTR_COOKIE whenever the cookie has been set,
regardless of error code.

route4_change() allocates a new filter and copies values from
the old one. After the new filter is inserted into the hash
table, the old filter should be removed and freed, as the final
step of the update.
However, the current code mistakenly removes the new one. This
looks apparently wrong to me, and it causes double "free" and
use-after-free too, as reported by syzbot.

hsr: fix several bugs in generic netlink callback
This patchset is to fix several bugs they are related in
generic netlink callback in hsr module.
1. The first patch is to add missing rcu_read_lock() in
hsr_get_node_{list/status}().
The hsr_get_node_{list/status}() are not protected by RTNL because
they are callback functions of generic netlink.
But it calls __dev_get_by_index() without acquiring RTNL.
So, it would use unsafe data.
2. The second patch is to avoid failure of hsr_get_node_list().
hsr_get_node_list() is a callback of generic netlink and
it is used to get node information in userspace.
But, if there are so many nodes, it fails because of buffer size.
So, in this patch, restart routine is added.
3. The third patch is to set .netnsok flag to true.
If .netnsok flag is false, non-init_net namespace is not allowed to
operate generic netlink operations.
So, currently, non-init_net namespace has no way to get node information
because .netnsok is false in the current hsr code.
Change log:
v1->v2:
- Preserve reverse christmas tree variable ordering in the second patch.

The hsr module has been supporting the list and status command.
(HSR_C_GET_NODE_LIST and HSR_C_GET_NODE_STATUS)
These commands send node information to the user-space via generic netlink.
But, in the non-init_net namespace, these commands are not allowed
because .netnsok flag is false.
So, there is no way to get node information in the non-init_net namespace.

Netlink support of extended packet number cipher suites,

* Setting and getting 64bit packet numbers with of SAs.
* Setting (only on SA creation) and getting ssci of SAs.
* Setting salt when installing a SAK.
Added 2 cipher suite identifiers according to 802.1AE-2018 table 14-1:
* MACSEC_CIPHER_ID_GCM_AES_XPN_128
* MACSEC_CIPHER_ID_GCM_AES_XPN_256

Support extended packet number cipher suites (802.1AEbw) frames handling.
This does not include the needed netlink patches.
* Added xpn boolean field to `struct macsec_secy`.
* Added ssci field to `struct_macsec_tx_sa` (802.1AE figure 10-5).
* Added ssci field to `struct_macsec_rx_sa` (802.1AE figure 10-5).
* Added salt field to `struct macsec_key` (802.1AE 10.7 NOTE 1).
* Created pn_t type for easy access to lower and upper halves.
* Created salt_t type for easy access to the "ssci" and "pn" parts.
* Created `macsec_fill_iv_xpn` function to create IV in XPN mode.
* Support in PN recovery and preliminary replay check in XPN mode.
In addition, according to IEEE 802.1AEbw figure 10-5, the PN of incoming
frame can be 0 when XPN cipher suite is used, so fixed the function
`macsec_validate_skb` to fail on PN=0 only if XPN is off.

The merge commit cb05c6c82fb0 (Merge 5.6-rc5 into tty-next) introduced a
double lock to set_selection_kernel. vc_sel.lock is locked both in
set_selection_kernel and its callee __set_selection_kernel now.
Remove the latter.

drivers/usb/gadget/legacy/Kconfig creates a 'choice' inside another
'choice'.
The outer choice: line 17 "USB Gadget precomposed configurations"
The inner choice: line 484 "EHCI Debug Device mode"
I wondered why the whole legacy gadget drivers reside in such a big
choice block.
This dates back to 2003, "[PATCH] USB: fix for multiple definition of
`usb_gadget_get_string'". [1]
At that time, the global function, usb_gadget_get_string(), was linked
into multiple drivers. That was why only one driver was able to become
built-in at the same time.
Later, commit a84d9e5361bc ("usb: gadget: start with libcomposite")
moved usb_gadget_get_string() to a separate module, libcomposite.ko
instead of including usbstring.c from multiple modules.
More and more refactoring was done, and after commit 1bcce939478f
("usb: gadget: multi: convert to new interface of f_mass_storage"),
you can link multiple gadget drivers into vmlinux without causing
multiple definition error.
This is the only user of the nested choice structure ever. Removing
this mess will make some Kconfig cleanups possible.

USB: changes for v5.7 merge window
Lots of changes on dwc3 this time, most of them from Thinh fixing a
bunch of really old mishaps on the driver.
DWC2 got support for STM32MP15 and a couple RockChip SoCs while DWC3
learned about Amlogic A1 family.
Apart from these, we have a few spelling fixes and other minor
non-critical fixes all over the place.

This makes it possible to take advantage of the function in
