[PATCH v3 0/3] i2c: PCF8584: Fix errors reported by checkpatch.pl

From: Cezar Chiru
Date: Mon Sep 08 2025 - 13:59:44 EST


Hello maintainers,

This patch series fixes 18 errors reported by checkpatch.pl on
drivers/i2c/algos/i2c-algo-pcf.c file.

The series v1->v2->v3 is a response to the discussion on the mailing
list with Markus Elfring that had comments on my earlier submisions. First
he suggested to split my initial submission in a patch series. Then he had
some valid points on imperative mood usage in commit messages, wrapping
commit message to 75 columns per line.

Here is a brief summary and Order of patches to be applied:

Patch 1/3: i2c: PCF8584: Fix debug macros defines of if statements
This patch encloses the debug macro defines of if statements in do-while
loops.

Patch 2/3: i2c: PCF8584: Fix do not use assignment in if conditional
This patch takes the assignement from if conditional and moves it by 1 line
up.

Patch 3/3: i2c: PCF8584: Fix space(s) required before or after different
operators
This patch adds space(s) around, before or after some operators

Testing:
*built kernel and modules with I2C_ALGOPCF=m and my 3 patches applied on
top.
*installed kernel and external modules generated by build on my laptop
*rebooted and loaded i2c-algo-pcf.ko with param i2c_debug=2/3/9.
*No success message related to i2c_algo_pcf was seen in dmesg but also no
errors.
*Module loading and unloading successfull.
*No PCF8584 Hardware was available.

Patches 1 and 3 report 4 and 6 warnings when running checkpatch on them.
But the warnings will be fixed in a new patchset that addresses fixing
warnings.
