pr_* versus dev_*

[Neshama Parhoti]

Which set of macros should I use in my driver ?

pr_info, pr_err, etc...  or dev_info, dev_err,    etc. ?

what are the advantages of the dev_* macros over the pr_* macros
(why does it take the device pointer as an argument) ?

obviously I don't have access to my device pointer in all my functions..
so pr_info is easier to use..
but if it's wanted, obviously I can arrange to have my device pointer
accessible..

thank you
