6.11-stable review patch. If anyone has any objections, please let me know.

From: Ma Ke make24@iscas.ac.cn
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.
