With all the three paths this is quite a handful of code, and it was mostly duplicated in two places. A follow-up patch would need to introduce a third copy of it. Therefore move the code into a helper function. There are two behavioral changes: - The format error now prints the string code as well, because it is easy to read. - The g_debug() in init_dumb_fb() is removed. Did not seem useful. https://gitlab.gnome.org/GNOME/mutter/merge_requests/810
