+Subject: fbdev/offb: Update expected device name
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+Origin: https://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev.git/commit?id=27c74ea74be805ccba1bc1a0a03cc79c51dca6ea
+
+Since commit 241d2fb56a18 ("of: Make OF framebuffer device names unique"),
+as spotted by Frédéric Bonnard, the historical "of-display" device is
+gone: the updated logic creates "of-display.0" instead, then as many
+"of-display.N" as required.
+
+This means that offb no longer finds the expected device, which prevents
+the Debian Installer from setting up its interface, at least on ppc64el.
+
+It might be better to iterate on all possible nodes, but updating the
+hardcoded device from "of-display" to "of-display.0" is confirmed to fix
+the Debian Installer at the very least.
