Hello maintainers,

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

The series PATCH v1 to PATCH v4 is a response to the discussion on the
mailing list with Markus Elfring who had comments on my earlier 
submissions. 
He suggested:
 -to split my initial submission in a patch series
 -had some valid points on imperative mood usage in commit messages
 -wrapping commit message to 75 columns per line
 -change some of the commit message to point usage of checkpatch.pl
The series PATCH v4 to PATCH v6 is a response to the discussion on the
mailing list with I2C SUBSYSTEM maintainer Wolfram Sang who requested
some changes:
He requested:
 - to remove debug macros from i2c-algo-pcf.c as no code change was done
 for almost 16 years.
 - remove wrapping paranthesis from value assigned of '(0)''.
 - resolve conficts caused by debug macros removal.
 - remove also printk and dev_dbg function calls related to DEB macros.

Here is a brief summary and order of patches to be applied:
Patch 1/3: i2c: pcf8584: Remove debug macros from i2c-algo-pcf.c
This patch remove the define of debug macros and also their usage from
code along with printk and dev_dbg function calls.

Patch 2/3: i2c: pcf8584: Fix do not use assignment inside 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 some binary operators.

Testing:
   *built kernel and modules with I2C_ALGOPCF=m and my 3 patches applied on
   top of 6.17.0-rc7.
   *installed kernel and external modules generated by build on my laptop
   *rebooted and loaded i2c-algo-pcf.ko without i2c_debug parameter.
   *when loading the .ko with i2c_debug parameter an error is seen in dmesg
   and this is expected as the parameter was removed.
   *No success message related to i2c_algo_pcf was seen in dmesg but also 
   no failures.
   *Module loading and unloading successful.
   *No PCF8584 Hardware was available.
