453495d4e7 USB-serial fixes for 5.5-rc7
Here are a few fixes for issues related to unbound port devices which
 could lead to NULL-pointer dereferences. Notably the bind attributes for
 usb-serial (port) drivers are removed as almost none of the drivers can
 handle individual ports going away once they've been bound.
 
 Included are also some new device ids.
 
 All but the unbound-port fixes have been in linux-next with no reported
 issues.

536a0d8e79 x86/resctrl: Check monitoring static key in the MBM overflow handler
Currently, there are three static keys in the resctrl file system:
rdt_mon_enable_key and rdt_alloc_enable_key indicate if the monitoring
feature and the allocation feature are enabled, respectively. The
rdt_enable_key is enabled when either the monitoring feature or the
allocation feature is enabled.

If no monitoring feature is present (either hardware doesn't support a
monitoring feature or the feature is disabled by the kernel command line
option "rdt="), rdt_enable_key is still enabled but rdt_mon_enable_key
is disabled.

MBM is a monitoring feature. The MBM overflow handler intends to
check if the monitoring feature is not enabled for fast return.

So check the rdt_mon_enable_key in it instead of the rdt_enable_key as
former is the more accurate check.

queue when a TX timeout event occurs. See commit 0290bd291c
("netdev: pass the stuck queue to the timeout handler") for more
details. Now, drivers don't need to identify which queue is stopped.
Drivers can simply use the queue index provided by dev_watchdog and

2da259c5fe fm10k: use txqueue parameter in fm10k_tx_timeout
Make use of the new txqueue parameter to the .ndo_tx_timeout function.
In fm10k_tx_timeout, remove the now unnecessary loop to determine which
Tx queue is stuck. Instead, just double check the specified queue

This could be improved further to attempt resetting only the specific
queue that got stuck. However, that is a much larger refactor and has
been left as a future improvement.

fdd64df7b9 USB: usbfs: Always unlink URBs in reverse order
When the kernel unlinks a bunch of URBs for a single endpoint, it
should always unlink them in reverse order.  This eliminates any
possibility that some URB x will be unlinked before it can execute but
the following URB x+1 will execute before it can be unlinked.  Such an
event would be bad, for obvious reasons.

Chris Dickens pointed out that usbfs doesn't behave this way when it
is unbound from an interface.  All pending URBs are cancelled, but in
the order of submission.  This patch changes the behavior to make the
unlinks occur in reverse order.  It similarly changes the behavior
when usbfs cancels the continuation URBs for a BULK endpoint.

c2c24edb1d arm64: csum: Fix pathological zero-length calls
In validating the checksumming results of the new routine, I sadly
neglected to test its not-checksumming results. Thus it slipped through
that the one case where @buff is already dword-aligned and @len = 0
manages to defeat the tail-masking logic and behave as if @len = 8.
For a zero length it doesn't make much sense to deference @buff anyway,
so just add an early return (which has essentially zero impact on
performance).

3bf8bdcf3b hwmon: (core) Do not use device managed functions for memory allocations
The hwmon core uses device managed functions, tied to the hwmon parent
device, for various internal memory allocations. This is problematic
since hwmon device lifetime does not necessarily match its parent's
device lifetime. If there is a mismatch, memory leaks will accumulate
until the parent device is released.

Fix the problem by managing all memory allocations internally. The only
exception is memory allocation for thermal device registration, which
can be tied to the hwmon device, along with thermal device registration
itself.

reg2volt returns the voltage that matches a given register value.
Converting this back the other way with volt2reg didn't return the same
register value because it used truncation instead of rounding.

This meant that values read from sysfs could not be written back to sysfs
to set back the same register value.

With this change, volt2reg will return the same value for every voltage
previously returned by reg2volt (for the set of possible input values)

e51a7dda29 hwmon: (nct7802) Fix non-working alarm on voltages
No alarm is reported by /sys/.../inX_alarm

In detail:

The SMI Voltage status register is the only register giving a status
for voltages, but it does not work like the non-SMI status registers
used for temperatures and fans.
A bit is set for each input crossing a threshold, in both direction,
but the "inside" or "outside" limits info is not available.
Also this register is cleared on read.
Note : this is not explicitly spelled out in the datasheet, but from
experiment.
As a result if an input is crossing a threshold (min or max in any
direction), the alarm is reported only once even if the input is
still outside limits. Also if the alarm for another input is read
before the one of this input, no alarm is reported at all.

ASoC: msm8916-wcd-analog: Add MIC BIAS Internal3
PM8916 has three TX inputs that each have an (optional) internal
RBIAS resistor. MIC BIAS Internal1/2 (for TX1/2) are already supported.
TX3 does not have its own MIC BIAS supply, instead it is also supplied
from MIC_BIAS1.

Now that we have simplified the MIC BIAS Internal* implementation
we can easily add support for it:

Add a MIC BIAS Internal3 supply that enables the internal RBIAS
resistor on TX3, and make sure to also enable the MIC_BIAS1 supply.

ASoC: msm8916-wcd-analog: Simplify MIC BIAS Internal
At the moment, MIC BIAS Internal* and MIC BIAS External* both reference
the same register, and have a part of their initialization sequence
duplicated.

For example, the sequence for enabling MIC BIAS Internal1 is:
  I1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN)
  I2. Enable internal RBIAS (TX1_INT_RBIAS_EN bit in CDC_A_MICB_1_INT_RBIAS)

The sequence for enabling MIC BIAS External1 is:
  E1. Enable MIC_BIAS1 supply (MICB_EN bit in CDC_A_MICB_1_EN)
  (E2. Ideally, make sure internal RBIAS is disabled. However, this should
   not happen in practice because DAPM will disable unused supplies...)

Right now we have:
  SND_SOC_DAPM_SUPPLY("MIC BIAS Internal1", CDC_A_MICB_1_EN, 7, 0, ...) // I1
  SND_SOC_DAPM_SUPPLY("MIC BIAS External1", CDC_A_MICB_1_EN, 7, 0, ...) // E1
and I2 is done in the PM event handler (pm8916_wcd_analog_enable_micbias_int1).

We can simplify this by defining a common DAPM supply for I1/E1 ("MIC_BIAS1"),
and one DAPM supply for I2 ("MIC BIAS Internal1"). Additional DAPM routes
ensure that we also enable the MIC_BIAS1 supply for the internal and external
pull up resistor.

Another advantage of this is that we now disable the internal RBIAS
when it is not needed. This makes it much easier to add support for
MIC BIAS Internal3 as a next step.

regulator: vctrl-regulator: Avoid deadlock getting and setting the voltage
`cat /sys/kernel/debug/regulator/regulator_summary` ends on a deadlock
when you have a voltage controlled regulator (vctrl).

The problem is that the vctrl_get_voltage() and vctrl_set_voltage() calls the
regulator_get_voltage() and regulator_set_voltage() and that will try to lock
again the dependent regulators (the regulator supplying the control voltage).

Fix the issue by exporting the unlocked version of the regulator_get_voltage()
and regulator_set_voltage() API so drivers that need it, like the voltage
controlled regulator driver can use it.
