[PATCH 1/2] staging: iio: cdc: ad7150: use pointer to shorten the line length

[Slawomir Stepien]

By using the pointer to channel attribute, we can now make the lines
short enough to eliminate the checkpatch.pl problem:

    CHECK: Alignment should match open parenthesis

[PATCH 2/2] staging: iio: cdc: ad7150: fix misaligned lines

[Slawomir Stepien]

These lines were misaligned, but the checkpatch.pl didn't indicate them
as such.

Hi,

Thanks for the patch. This looks good. But maybe a small suggestion further
improvement.

Instead of taking a pointer, just take the value of the channel index and
use that. The generated code should be very similar but its a bit nicer to read.

OK. I've been thinking about that for a moment, but in the end decided to go
with the pointer. I don't mind the value. I'll prepare v2. Thank you.
