6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ma Ke <make24@xxxxxxxxxxx>
commit 1ccc9e476ce76e8577ba4fdbd1f63cb3e3499d38 upstream.
devm_kasprintf() can return a NULL pointer on failure but this returned
value is not checked. Fix this lack and check the returned value.
Found by code review.
