Some of DAMON sysfs interface code is not handling return values from some functions. As a result, confusing user input handling or NULL-dereference is possible. Check those properly. Please note that these patches are not cleanly applicable on mm-unstable since mm-unstable has dropped the mainline-merged patches and rebased on v6.6, while some DAMON patches that these patches are depend on are merged in the mainline after v6.6. I confirmed these patches can cleanly applied on latest mainline, or mm-stable-2023-11-01-14-33.
