Hi Tudor,

please improve your patch description. Better omit what you are changing 
as this can be seen in the change itself. Do focus on why this patch 
makes the code better. Please use a full sentence starting with an upper 
letter and ends with a ".".

If you send in a second version of this patch please use a change 
history. Description from Dan under:
https://staticthinking.wordpress.com/2022/07/27/how-to-send-a-v2-patch/

Thanks for your support.

Bye Philipp
