[PATCH] pr_debug: check pr_debug() arguments
check pr_debug() arguments
When DEBUG isn't defined pr_debug() is defined away as an empty macro. By

Instead let's make it an empty inline which checks arguments and mark it so gcc
can check the format specification.
This results in a seemingly insignificant code size increase. A x86-64
