48a24fd21d iio: adc: ad7625: Stop using iio_device_claim_direct_scoped() 
This complex cleanup.h use case of conditional guards has proved
to be more trouble that it is worth in terms of false positive compiler
warnings and hard to read code.

Move directly to the new claim/release_direct() that allow sparse
to check for unbalanced context.

8ec5a6fc3b iio: adc: ad7625: drop BSD license tag 
The ad7625 driver was submitted under a dual BSD/GPL license, but this
isn't a requirement for the code, and adds extra complexity. To make it
consistent with similar drivers, drop the BSD tag and leave it as
GPL-2.0-only.

cdd30ebb1b module: Convert symbol namespace to string literal 
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Scripted using

  git grep -l -e MODULE_IMPORT_NS -e EXPORT_SYMBOL_NS | while read file;
  do
    awk -i inplace '
      /^#define EXPORT_SYMBOL_NS/ {
        gsub(/__stringify\(ns\)/, "ns");

b7ffd0fa65 iio: adc: ad7625: add driver 
Add a driver for the AD762x and AD796x family of ADCs. These are
pin-compatible devices using an LVDS interface for data transfer,
capable of sampling at rates of 6 (AD7625), 10 (AD7626), and 5
(AD7960/AD7961) MSPS, respectively. They also feature multiple voltage
reference options based on the configuration of the EN1/EN0 pins, which
can be set in the devicetree.
