6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Yi Yang <yiyang13@xxxxxxxxxx> [ Upstream commit 5a985960a4dd041c21dbe9956958c1633d2da706 ] devm_kasprintf() returns a pointer to dynamically allocated memory which can be NULL upon failure. Ensure the allocation was successful by checking the pointer validity.
