Resolving the following audit denials:

- [    6.450477] type=1400 audit(1699468821.992:6): avc:  denied
{ read } for comm="aocd" name="notify_timeout_aoc_status"
dev="sysfs" ino=78572 scontext=u:r:aocd:s0
tcontext=u:object_r:sysfs_aoc:s0 tclass=file permissive=0

- type=1107 audit(0.0:9): uid=0 auid=4294967295 ses=4294967295
subj=u:r:init:s0 msg='avc: denied  { set } for

pid=1035 uid=0 gid=0 scontext=u:r:aocd:s0
tcontext=u:object_r:vendor_default_prop:s0
