master 97b8c0a: Make hi-lock-face-buffer more resilient

[Lars Ingebrigtsen]

branch: master
commit 97b8c0adc1d6ce42c43829e1270c0ccd13a82382
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Make hi-lock-face-buffer more resilient
    
    * lisp/hi-lock.el (hi-lock-face-buffer): If given a face name a
    string, convert it to a symbol first, as later usage of this
    expects a symbol and not a string (bug#43339).
