Subject: [PATCH 00/17] fbdev: Remove FBINFO_DEFAULT and FBINFO_FLAG_DEFAULT flags
Date:   Mon, 10 Jul 2023 14:50:04 +0200

Remove the unused flags FBINFO_DEFAULT and FBINFO_FLAG_DEFAULT from
fbdev and drivers, as briefly discussed at [1]. Both flags were maybe
useful when fbdev had special handling for driver modules. With
commit 376b3ff54c9a ("fbdev: Nuke FBINFO_MODULE"), they are both 0
and have no further effect.

Patches 1 to 7 remove FBINFO_DEFAULT from drivers. Patches 2 to 5
split this by the way the fb_info struct is being allocated. All flags
are cleared to zero during the allocation.

Patches 8 to 16 do the same for FBINFO_FLAG_DEFAULT. Patch 8 fixes
an actual bug in how arch/sh uses the tokne for struct fb_videomode,
which is unrelated.

Patch 17 removes both flag constants from <linux/fb.h>
