[PATCH v5 0/3] iio: frequency: ad9523: fix checkpatch warnings

[Bhargav Joshi]

These patches address several checkpatch warnings in the ad9523 driver.

Patch 1: Updated the macros to properly use their argument x.
Patch 2: Fixed the multi-line pointer dereferences.
Patch 3: Updated symbolic permissions to octal (0444/0200).

Changes in v5:
- Reflowed all commit messages to properly wrap near 72 characters as
requested.
- Collected Reviewed-by tags for patches 1 and 3.

Changes in v4:
- Used full name for SoB 

Changes in v3:
- Patch 1: updated macros to use '(x)' instead of 'x'.
- Patch 2: collected reviewed-by (no code changes).
- Patch 3: fixed vertical spacing and broken indentation.

  iio: frequency: ad9523: fix implicit variable usage in macros
  iio: frequency: ad9523: avoid multiple line dereferences for pdata
  iio: frequency: ad9523: fix checkpatch warnings for symbolic

[PATCH v5 1/3] iio: frequency: ad9523: fix implicit variable

[Bhargav Joshi]

Macros AD9523_CLK_DIST_DIV_PHASE_REV(x) and AD9523_CLK_DIST_DIV_REV(x)
implicitly relied on variable named 'ret' instead of using passed
argument '(x)'. Update the macros to explicitly use the argument '(x)'
for their operations.

This also resolves the following checkpatch.pl warning: Argument '(x)'
is not used in function-like macro

[PATCH v5 2/3] iio: frequency: ad9523: avoid multiple line

[Bhargav Joshi]

Platform data pointer dereferences for pll1_charge_pump_current_nA and
pll2_charge_pump_current_nA were split across multiple lines. Bring the
dereference chains onto a single line.

This resolves the following checkpatch.pl warnings:
WARNING: Avoid multiple line dereference - prefer 'pdata->pll1_charge_pump_current_nA'
WARNING: Avoid multiple line dereference - prefer 'pdata->pll2_charge_pump_current_nA'

Subject: [PATCH v5 3/3] iio: frequency: ad9523: fix checkpatch warnings
for symbolic permissions

The driver currently defines device attributes using symbolic permission
flags (S_IRUGO and S_IWUSR). Update these to use octal permissions (0444
and 0200) to resolve checkpatch warnings.

Thanks for the update, it still needs more amendments (something even
went wrong in patch 3).
