That patch is simply wrong. Kernel logging system is able to add
function name automatically - it should not be defined manually for
debug logging.
See kernel documentation:
Documentation/dynamic-debug-howto.txt
around the line 213.
----------------------------------
The flags are:
p enables the pr_debug() callsite.
f Include the function name in the printed message
l Include line number in the printed message
m Include module name in the printed message
t Include thread ID in messages not generated from interrupt context
_ No flags are set. (Or'd with others on input)
