5aadd5c692 staging: qlge/qlge_ethtool.c: Switch from strlcpy to strscpy 
strlcpy is marked as deprecated in Documentation/process/deprecated.rst,
and there is no functional difference when the caller expects truncation
(when not checking the return value). strscpy is relatively better as it
also avoids scanning the whole source string.

This silences the related checkpatch warnings from:
5dbdb2d87c ("checkpatch: prefer strscpy to strlcpy")

The debugging code in the following ifdef land
 - QL_ALL_DUMP
 - QL_REG_DUMP
 - QL_DEV_DUMP
 - QL_CB_DUMP
 - QL_IB_DUMP
 - QL_OB_DUMP

becomes unnecessary because,
 - Device status and general registers can be obtained by ethtool.
 - Coredump can be done via devlink health reporter.
 - Structure related to the hardware (struct ql_adapter) can be obtained
   by crash or drgn.

Initialize devlink health dump framework for the qlge driver so the
coredump could be done via devlink.

struct qlge_adapter is now used as the private data structure of
struct devlink so it could exist independently of struct net_device
and devlink reload could be supported in the future. The private data
of PCIe driver now points to qlge_adapter.

Since devlink_alloc will zero out struct qlge_adapter, memset in

684ceb81dc staging: vc4_services: bcm2835-audio: Add SNDRV_PCM_INFO_BATCH flag 
Playing audio with PulseAudio and the bcm2835-pcm driver results
in distorted sound. Timer-based scheduling does not properly work
with bcm2835-pcm since configuring PulseAudio with tsched=0
avoids this problem.

Setting the SNDRV_PCM_INFO_BATCH flag prevents PulseAudio to use
timer-based scheduling by default. Settings this flag makes audio
works out of the box.

During the driver refactor, a regression broke the logic inside
hi6421_spmi_regulator_get_optimum_mode(). Basically, if a LDO
has eco_uA == 0, it doesn't support economic mode. So, it should
return REGULATOR_MODE_NORMAL.

If economic mode is supported, it can return either
REGULATOR_MODE_IDLE or REGULATOR_MODE_NORMAL, depending on the
load current.

fd765da060 staging: hikey9xx: hi6421v600-regulator: fix delay logic 
The original driver, which can be seen at
commit 42f24d9d44 ("staging: regulator: add a regulator driver for HiSilicon 6421v600 SPMI PMIC")
had a complex logic to ensure that there won't be multiple power
enable/disable commands running at the same time. At the original
logic, it were ensured that:

- a next power up/down would wait for at least the on/off period;
- an extra delay would be granted. It turns that such extra delay
  has a value of zero, but it was relying on gettimeofday()
  call, which can take some time.

This was later simplified, but there are still some possible
issues. In order to avoid that, let's simply add a delay
to wait for the power up line to stabilize after powering up
a device.

b4783da2c1 staging: comedi: adv_pci_dio: Support falling edge triggers 
The interrupt support for Advantech PCI-1730 currrently supports only
rising edge inputs for the trigger sources.  Each of four interrupt
sources (each with its own Comedi subdevice) can be set to trigger on
either a rising edge or a falling edge.  Add support for choosing the
edge during set-up of the asynchronous command for the subdevice, using
the `CR_INVERT` bit of `scan_begin_arg` to indicate falling edge when
set, or rising edge when clear.  Also allow the `CR_EDGE` bit to be set,
but ignore it.  All other bits of `scan_begin_arg` must be zero.

2e0e629d0f staging: comedi: adv_pci_dio: Add interrupt handling for PCI-1730 
On the Advantech PCI-1730, four digital inputs (DI0, DI1, IDI0 and IDI1)
can be used as external interrupt sources.  Each input can be programmed
to latch an interrupt bit on either a rising edge or a falling edge (but
not both).

Add a new Comedi subdevice for each interrupt source, supporting the
asynchronous command interface.  Subdevices 5, 6, 7 and 8 are for
interrupt sources DI0, DI1, IDI0 and IDI1.  They each write the state of
16 digital inputs to the subdevice's data buffer each time the
corresponding interrupt occurs.  (For DI0 and DI1, use the 16
non-isolated digital inputs.  For IDI0 and IDI1, use the 16 isolated
digital inputs.)

Currently, only rising edge triggers are supported.  Support could be
added for the PCI-1733 and PCI-1736.

115dbad485 staging: comedi: adl_pci7x3x: Add interrupt handling for PCI-7230 
On the ADLink PCI-7230, digital input channels 0 and 1 can be used as
external interrupt sources.  A rising edge on each input latches a
corresponding local interrupt input of the PCI interface chip.  Writing
a "clear IRQ" register clears both latches.

Add a new Comedi subdevice for each interrupt source, supporting the
asynchronous command interface.  This writes the state of the 16 digital
inputs to the subdevice's data buffer each time the corresponding
interrupt occurs.

This could be adapted to support the PCI-7233, PCI-7432 and PCI-7433
boards too.  They all have two interrupt sources, although for PCI-7233
each interrupt source is triggered by a change of state of 16 digital
inputs (0-15 and 16-31).  The "clear IRQ" register is at a different
offset for some boards.

61834c967a staging: rtl8723bs: wifi_regd.c: Fix incorrect number of regulatory rules 
The custom regulatory ruleset in the rtl8723bs driver lists an incorrect
number of rules: one too many. This results in an out-of-bounds access,
as detected by KASAN. This was possible thanks to the newly added support
for KASAN on ARMv7.

Fix this by filling in the correct number of rules given.
