55f82c00b2 iio: dac: ltc2632: remove some unused defines
These two defines are unused since the driver was introduced in commit
02b829f9e1 ("iio: dac: Add support for ltc2632 DACs").

9f15a4a0ad iio: dac: ltc2632: add support for LTC2636 family
The only difference between LTC2632 and LTC2636 is that the former has
two DAC channels while the latter has eight.

f243d0f0bd iio: dac: ltc2632: drop some duplicated data
The channel data for ltc2632l12 and ltc2632h12 are identical. So there
is no gain in using two different (but identical) channel descriptions.
The only side effect of this change is some memory savings.

3723c63247 treewide: convert ISO_8859-1 text comments to utf-8
Almost all files in the kernel are either plain text or UTF-8 encoded.  A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.

This converts them all to UTF-8 for consistency.

5f0d4fd6b2 iio: dac: ltc2632 remove redundant pointer chip_info and spi_dev_id
Pointers chip_info and spi_dev_id are being assigned but are never used
hence they are redundant and can be removed.

Cleans up clang warning:
warning: variable 'chip_info' set but not used [-Wunused-but-set-variable]

ea9e3f3588 iio:dac: drop assignment of iio_info.driver_module
The equivalent of this is now done via macro magic when
the relevant register call is made.  The actual structure
element will shortly go away.
