The slimbus mux put operation unconditionally reports a change in value
which means that spurious events are generated. Fix this by exiting early
in that case.

Currently in slim_rx_mux_put, an RX channel gets added to a new list
even if it is already in one. This can mess up links and make either
it, the new list head, or both, get linked to the wrong entries.
This can cause an entry to link to itself which in turn ends up
making list_for_each_entry in other functions loop infinitely.
To avoid issues, always remove the RX channel from any list it's in
before adding it to a new list.

Move the size checks prior to allocating memory as these checks do not need
the data to be allocated and in case of an error we would not need to free
the allocation.
The max size must not be less than the size of
struct sof_ipc_ctrl_data + struct sof_abi_hdr as the ABI header needs to
be present under all circumstances.
The check was incorrectly used or between the two size checks.

Renesas is the only user of ak4613 on upstream for now, and
commit f28dbaa958fbd8 ("ASoC: ak4613: add TDM256 support")
added TDM256 support. Renesas tested part of it, because of

It was assuming ak4613 is probed via Audio-Graph-Card, but it
might be probed via Simple-Audio-Card either.
It will indicates WARNING in such case. This patch fixup it.

The .set_jack_detect() codec component callback is invoked during card
registration, which happens when the machine driver is probed.
The issue is that this callback can race with the bus suspend/resume,
and IO timeouts can happen. This can be reproduced very easily if the
machine driver is 'blacklisted' and manually probed after the bus
suspends. The bus and codec need to be re-initialized using pm_runtime
helpers.
Previous contributions tried to make sure accesses to the bus during
the .set_jack_detect() component callback only happen when the bus is
active. This was done by changing the regcache status on a component
remove. This is however a layering violation, the regcache status
should only be modified on device probe, suspend and resume. The
component probe/remove should not modify how the device regcache is
handled. This solution also didn't handle all the possible race
conditions, and the RT700 headset codec was not handled.
This patch tries to resume the codec device before handling the jack
initializations. In case the codec has not yet been initialized,
pm_runtime may not be enabled yet, so we don't squelch the -EACCES
error code and only stop the jack information. When the codec reports
as attached, the jack initialization will proceed as usual.

Realtek headset codec drivers typically check if the card is
instantiated before proceeding with the jack detection.
The rt700, rt711 and rt711-sdca are however missing a check on the
card pointer, which can lead to NULL dereferences encountered in
driver bind/unbind tests.

1. Correct UART clocks on Exynos7885. Although the initial, fixed
DTS commit is from v5.18, the issue will be exposed with a upcoming fix
to Exynos7885 clock driver, so we need to correct the DTS earlier.

address of `env->prog` is updated. This address is updated upon BPF
program reallocation.
Reallocation is handled by bpf_prog_realloc(), which reuses old memory

We use cifs_tcp_ses_lock to protect a lot of things.
Not only does it protect the lists of connections, sessions,
tree connects, open file lists, etc., we also use it to
protect some fields in each of it's entries.
In this case, cifs_mark_ses_for_reconnect takes the
cifs_tcp_ses_lock to traverse the lists, and then calls
cifs_update_iface. However, that can end up calling
cifs_put_tcp_session, which picks up the same lock again.
Avoid this by taking a ref for the session, drop the lock,
and then call update iface.
Also, in cifs_update_iface, avoid nested locking of iface_lock
and chan_lock, as much as possible. When unavoidable, we need
to pick iface_lock first.

Get rid of some clunky open coded arithmetic on section addresses, by
emitting the trampoline data variables into a separate, dedicated r/o
data section, and putting it at the next page boundary. This way, we can
access the literals via single LDR instruction.
While at it, get rid of other, implicit literals, and use ADRP/ADD or
MOVZ/MOVK sequences, as appropriate. Note that the latter are only
supported for CONFIG_RELOCATABLE=n (which is usually the case if
CONFIG_RANDOMIZE_BASE=n), so update the CPP conditionals to reflect
this.

The complete() function may be called even though request is not
completed. In this case, it's necessary to check request status so
as not to set device address wrongly.

Re-reading a recently merged fix to the raw_gadget driver showed that
it inadvertently introduced a double-free bug in a failure pathway.
If raw_ioctl_init() encounters an error after the driver ID number has
been allocated, it deallocates the ID number before returning. But
when dev_free() runs later on, it will then try to deallocate the ID
number a second time.
Closely related to this issue is another error in the recent fix: The
ID number is stored in the raw_dev structure before the code checks to
see whether the structure has already been initialized, in which case
the new ID number would overwrite the earlier value.
The solution to both bugs is to keep the new ID number in a local
variable, and store it in the raw_dev structure only after the check
for prior initialization. No errors can occur after that point, so
the double-free will never happen.

When using usb-role-switch, D+ pull-up is set as soon as DTCL_SFTDISCON is
cleared, whatever the vbus valid signal state is. The pull-up should not
be set when vbus isn't present (this is determined by the drd controller).
This patch ensures that B-Session (so Peripheral role + vbus valid signal)
is valid before clearing the DCTL_SFTDISCON bit when role switch is used.
Keep original behavior when usb-role-switch isn't used.

====================
mlxsw: Unified bridge conversion - part 3/6
This is the third part of the conversion of mlxsw to the unified bridge
model.
Like the second part, this patchset does not begin the conversion, but
instead prepares the FID code for it. The individual changes are
relatively small and self-contained with detailed description and
motivation in the commit message.

The function was designed to configure both VLAN and FID RIFs, but
currently the driver does not use VLAN RIFs. Instead, it emulates VLAN
RIFs using FID RIFs.
As part of the conversion to the unified bridge model, the driver will
need to use VLAN RIFs, but they will be configured differently from FID
RIFs.
As a preparation for this change, rename the function to reflect the
fact that it is specific to FID RIFs and do not pass the RIF type as an
argument.
This leaves mlxsw_reg_ritr_fid_set() unused, so remove it.

Currently, the driver emulates 802.1Q FIDs using 802.1D FIDs. As such,
the RIFs configured on top of these FIDs are FID RIFs and not VLAN RIFs.
As part of converting the driver to the unified bridge model, 802.1Q
FIDs and VLAN RIFs will be used.
As a preparation for this change, rename the emulated VLAN RIFs from
'MLXSW_SP_RIF_TYPE_VLAN' to 'MLXSW_SP_RIF_TYPE_VLAN_EMU'. After the
conversion the emulated VLAN RIFs will be removed.

Egress VID for layer 2 multicast is determined from two tables, the MPE
and PGT tables. The MPE table is a two dimensional table indexed by local
port and SMPE index, which should be thought of as a FID index.
In Spectrum-1 the SMPE index is derived from the PGT entry, whereas in
Spectrum-2 and newer ASICs the SMPE index is a FID attribute configured
via the SFMR register.
The validity of the SMPE index in SFMR is influenced from two factors:
1. FID family. SMPE index is reserved for rFIDs, as their flooding is
handled by firmware.
2. ASIC generation. SMPE index is always reserved for Spectrum-1.
As such, the validity of the SMPE index should be an attribute of the FID
family and have different arrays of FID families per-ASIC type.
As a preparation for SMPE index configuration, create separate arrays of
FID families for different ASICs.

The function configures {Port, VID}->FID classification entries using
the SVFA register. In the unified bridge model such entries will need to
be programmed with an ingress RIF parameter, which is a FID attribute.
As a preparation for this change, pass the FID structure itself to the
function.
