6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ma Ke make24@iscas.ac.cn
commit 665a58fe663ac7a9ea618dc0b29881649324b116 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.
