a66111446d staging: greybus: 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")

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.

75d39eb538 staging: hikey9xx: hi6421v600-regulator: fix get_optimum_mode 
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.

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.
