My point was that with your patch, the kmemleak kernel messages with
pr_info were something like:

kmemleak: kmemleak: unreferenced object ...
kmemleak: comm ...
kmemleak: backtrace:

After dropping "kmemleak: " in the print_helper() call, kernel messages
become (which I find nicer):

kmemleak: unreferenced object ...
kmemleak: comm ...
kmemleak: backtrace:

For the seq_printf() we really don't need the "kmemleak: " prefix since
you read a kmemleak-specific file anyway. With my modification, the seq
output becomes:

unreferenced object ...
comm ...

i.e. without the "kmemleak: " prefix on the "unreferenced ..." line.
