Subject: [PATCH 0/3] mm/damon/sysfs: fix unhandled return values

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.

  mm/damon/sysfs: check error from damon_sysfs_update_target()
  mm/damon/sysfs-schemes: handle tried regions sysfs directory
    allocation failure
  mm/damon/sysfs-schemes: handle tried region directory allocation
    failure
