6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ma Ke <make24@xxxxxxxxxxx>
commit 267efeda8c55f30e0e7c5b7fd03dea4efec6916c 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.
