Subject: ; Avoid compiler warnings in 'extend_face_to_end_of_line'
X-Git-Tag: emacs-29.0.90~1616^2~257

; Avoid compiler warnings in 'extend_face_to_end_of_line'

* src/xdisp.c (extend_face_to_end_of_line): Return if no
default_face is cached or could be realized.  This avoids
compilation warnings about NULL pointer dereferences.
