master 79c0e78460: Pacify warnings from gcc 12 in encode_coding_object

[Lars Ingebrigtsen]

branch: master
commit 79c0e78460b86d6efef31f65dcb16ab6b89b8551
Author: Matt Armstrong <matt@rfc20.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Pacify warnings from gcc 12 in encode_coding_object
    
    * src/coding.c (encode_coding_object): Mark saved_pt_byte with UNINIT
    to silence a false alarm from -Wmaybe-uninitialized.  This was already
    done in decode_coding_object.  The fix is correct because saved_pt is
    used as a sentinel before saved_pt_byte is used (bug#57219).
