[PATCH] scripts/kernel-doc: drop "_noprof" on function prototypes

[Randy Dunlap]

Memory profiling introduces macros as hooks for function-level
allocation profiling[1]. Memory allocation functions that are profiled
are named like xyz_alloc() for API access to the function. xyz_alloc()
then calls xyz_alloc_noprof() to do the allocation work.

The kernel-doc comments for the memory allocation functions are
introduced with the xyz_alloc() function names but the function
implementations are the xyz_alloc_noprof() names.
This causes kernel-doc warnings for mismatched documentation and
function prototype names.
By dropping the "_noprof" part of the function name, the kernel-doc
function name matches the function prototype name, so the warnings
are resolved.

a. Suren, Kent, feel free to correct my comments on memory profiling.
I haven't read the documentation in a few weeks.

b. There are some instances of the kernel-doc function name including
"_noprof". Suren is correcting those cases so that all _noprof warnings
will be resolved.
