After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

Contrary to what the naming might suggest, devm_regulator_get_optional
returns -ENODEV in case the regulator is not found which will trigger
probe error in this driver.
Use devm_regulator_get instead which will return a dummy regulator that
we can just use as if it was a proper regulator.

On some boards interrupt type might be different than falling edge,
like hardcoded in driver. Leave interrupt flags as they were pre-configured
from the device-tree. If they're not provided, default to falling edge
interrupts.

wait_for_completion_timeout() returns unsigned long not int.
It returns 0 if timed out, and positive if completed.
The check for <= 0 is ambiguous and should be == 0 here
indicating timeout which is the only error case.

Previously inconsistent with a space after { but not before }.
Tidy that up to avoid providing a bad example that might get copied
into other drivers.

Add i2c_device_id table for the vl53l0x-i2c driver,
helps in device instantiation using i2c_new_client_device()
or from userspace in cases where device-tree based description
is not possible now, like device(s) on a gbphy i2c adapter
created by greybus.

VL53L0X can be configured to use interrupt pin (GPIO1)
to notify host about readiness of new measurement.
If interrupt pin is not specified, driver still uses polling.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

This driver was originally written by ST in 2016 as a misc input device
driver, and hasn't been maintained for a long time. I grabbed some code
from it's API and reformed it into an iio proximity device driver.
This version of driver uses i2c bus to talk to the sensor and
polling for measuring completes, so no irq line is needed.
It can be tested with reading from
/sys/bus/iio/devices/iio:deviceX/in_distance_input
