When user tried to read some fields like hysteresis from IIO sysfs on some
systems, it fails. The reason is that this field is a byte field and caller
of sensor_hub_get_feature() passes a buffer of 4 bytes. Here the function
sensor_hub_get_feature() copies the single byte from the report to the
caller buffer and returns "1" as the number of bytes copied. So caller
can use the return value.

But this is done by multiple callers, so if we just change the
sensor_hub_get_feature so that caller buffer is initialized with 0s
then we don't to change all functions.

Now with musb driver implementing generic session bit based
PM, we need to have the USB PHYs behaving in a sane way for
platforms implementing PM.

Currently twl4030-usb enables PM in twl4030_phy_power_on()
and then disables it in twl4030_phy_power_off(). This will
block PM runtime for the SoC when no cable is connected.

Fix the issue by moving PM runtime autosuspend call to
happen where it gets called in twl4030_phy_power_on().

Note that this patch should not be backported to anything
before commit 467d5c98 ("usb: musb: Implement session bit

With a USB hub disconnected, devctl can be 0x19 for about a second
on am335x and will stay forever on at least omap3. And we get no
further interrupts when devctl session bit clears. This keeps
PM runtime active.

Let's fix the issue by polling devctl until the session bit clears
or times out. We can do this by making musb->irq_work into
delayed_work.

And with the polling implemented, we can now also have the quirk
for invalid VBUS it to avoid disconnecting too early while VBUS
is ramping up.

I did not notice that as I did not have CONFIG_DEBUG_ATOMIC_SLEEP enabled.
And looks like also musb_gadget_queue() suffers from the same problem.

Let's fix the issue by using a list of delayed work then call it on
resume. Note that we want to do this only when musb core and it's
parent devices are awake, and we need to make sure the DSPS glue
timer is stopped as noted by Johan Hovold <johan@kernel.org>.
Note that we already are re-enabling the timer with mod_timer() in
dsps_musb_enable().

Later on we may be able to remove other delayed work in the musb driver
and just do it from pending_resume_work. But this should be done only
for delayed work that does not have other timing requirements beyond
just being run on resume.

We currently have a fundamental problem in how we treat the CPU port and
its VLAN membership. As soon as a second VLAN is configured to be
untagged, the CPU automatically becomes untagged for that VLAN as well,
and yet, we don't gracefully make sure that the CPU becomes tagged in
the other VLANs it could be a member of. This results in only one VLAN
being effectively usable from the CPU's perspective.

Instead of having some pretty complex logic which tries to maintain the
CPU port's default VLAN and its untagged properties, just do something
very simple which consists in neither altering the CPU port's PVID
settings, nor its untagged settings:

- whenever a VLAN is added, the CPU is automatically a member of this
  VLAN group, as a tagged member
- PVID settings for downstream ports do not alter the CPU port's PVID
  since it now is part of all VLANs in the system

This means that a typical example where e.g: LAN ports are in VLAN1, and
WAN port is in VLAN2, now require having two VLAN interfaces for the
host to properly terminate and send traffic from/to.
