6.5-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.
Fixes: 1e4d3ba66888 ("mtd: rawnand: meson: fix the clock")
