You seem to have several of these patches, they should be sent in a
series with the series patch subject (for example):
[PATCH net-next 0/n] fix up casts on kfree

Did you use a coccinelle script to find these? 

They could all have Fixes tags. I'd resend the whole bunch as a series.

Since this has no functional change, you could mention that in the
series commit message text.

Commits with no functional change generally should
not be marked with Fixes:

And some wrapper functions might as well be removed
and just kfree used in-place instead.
