We need the char-misc fixes in here as well.

This is a frequent minor comment in reviews, so start cleaning up
existing drivers in the hope we get fewer cases of cut and paste.
There are not kernel wide rules for these, but for IIO the style
that I prefer (and hence most common) is:
- Space after { and before }
- No comma after terminator { }
This may cause merge conflicts but they should be trivial to resolve
hence I have not broken this into per driver patches.

The current implementation attempts to recover from an eventual glitch
in the clock by checking frstdata state after reading the first
channel's sample: If frstdata is low, it will reset the chip and
return -EIO.
This will only work in parallel mode, where frstdata pin is set low
after the 2nd sample read starts.
For the serial mode, according to the datasheet, "The FRSTDATA output
returns to a logic low following the 16th SCLK falling edge.", thus
after the Xth pulse, X being the number of bits in a sample, the check
will always be true, and the driver will not work at all in serial
mode if frstdata(optional) is defined in the devicetree as it will
reset the chip, and return -EIO every time read_sample is called.
Hence, this check must be removed for serial mode.

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

Do not trust the fact that iio.h includes of.h which in turn includes
all the headers we are relying on.
The ultimate goal is to actually drop of.h from iio.h.

In order to avoid unnecessary pollution of the global symbol namespace
move the core/library functions into a specific namespace and import
that into the various bus specific device drivers that use them.

We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.
// <smpl>
@@
expression ret;
struct platform_device *E;
@@
ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);
if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>
While we're here, remove braces on if statements that only have one
statement (manually).
