SubjectRe: [PATCH] Replaced hard coded function names in debug messages with __func__ macro.

Greetings Daniel,
Thank you very much for the response. So, should I just revert back to the original
all the changes in places where I replace hard coded functions names with  __func__?

Kind regards,

Tabot Kevin.
