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.

The light sensor needs the regulators to be enabled which means
the runtime PM needs to be on. This only happened when the
proximity part of the chip was enabled.
As fallout from this change, only report changes to the prox
state in the interrupt handler when it is explicitly enabled.

The look-up-table for currens to lux is simply specifying
all currents from 5..47 mA, if we add some values for 0..5
we can just select the index for the lux value in an array
from the mA value. Use clamp() to get the value in the
range of values in the array.

This driver handles two different Sharp sensors that have been
proposed for merging to the mainline kernel over the years, and
already has a limited proximity-only driver in the input
subsystem.
These components are completely different from the confusingly
similarly named Sharp GP2AP020A00F, for which we have a driver
in drivers/iio/light/gp2ap020a00f.c
The two components GP2AP002A00F and GP2AP002S00F are
distinctively different but similar: they share the same set of
registers but differ slightly in the I2C protocol.
Instead of the approach by the previous input driver, we create
a combined IIO proximity and light sensor driver.
The plan is to merge this driver and delete the input driver.
The pieces for the driver are picked all over the place after
researching and grepping through a few different vendor trees
and driver submissions.
We merge it under the light sensors because:
- It has similarities with the Capella CM3605 light sensor and
proximity driver which is there.
- It is related to the GP2AP020A00F driver which is also there.
This driver was tested with the Samsung GT-S7710 mobile phone
which has the GP2AP002S00F proximity sensor mounted.
The suspend/resume cycle will disable the interrupt from the
sensor. If someone would desire to use this interrupt for
wakeup, the driver will need modifications.
