Description of problem:
Happened after reboot
SELinux is preventing iw from 'write' accesses on the file /run/tlp/lock_tlp.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/run/tlp/lock_tlp default label should be tlp_var_run_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do
# /sbin/restorecon -v /run/tlp/lock_tlp

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that iw should be allowed write access on the lock_tlp file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'iw' --raw | audit2allow -M my-iw
# semodule -X 300 -i my-iw.pp
