No, just use the built-in dynamic debug code in the kernel, no need to
provide any new macros or functions or most importantly, no new Kconfig
options.
New macro (oz_trace) is being used as pointer to "struct device *" is
not available in all functions for dev_dbg() function.
Please let me know if there is better way to handle this, I will be
happy to rework on this.
As well new Kconfig option was added to pass CFLAGS to compiler, so that
dev_dbg will get compiled on system where DYNAMIC_DEBUG is not defined.
I was assuming that it is a standard practice, as I can find similar
Kconfig option for other drivers. Or am I wrong in my understanding ?
Main idea here is to replace printk with dev_dbg(), which gives us
option to enable individual log during runtime if DYNAMIC_DEBUG is
enabled & provide mechanism to compile this when DYNAMIC_DEBUG is not
enabled.
Again many of these logs will be removed in future, as currently there
are too many logs which are not required, hence idea is to only change
macro & then remove remaining logs in future.
