This patch tries to cleanup some function description:
* function name mismatch
* parameter name mismatch
* parameter all end up with ':'
* not prefix '*' if parameter is a pointer
There is still some missing description of parameters, I didn't add them
since I am not sure the exact meaning.

v3:
* s/interface/function/ in change log
v2:
* not change them to kernel doc since they are inline functions
