maybe it is more simple to use kasprintf here ?
just my 2 cents,

I am new to kasprintf. I think we need to make sure of freeing memory
allocated using kasprintf.

There is also devm_kasprintf().
But these are really two separate things. One thing is the missing NULL
check, which is a bug fix and is fixed by your patch. The other thing is the
conversion to kasprintf() which is a code cleanup and should be done in a
separate patch.

hi,
thx for the hint:
never read about devm_kasprintf().
ntl my mail was intended as hint about asprintf() not about the patch.
