With this series on top of 5.19-rc1, the only remaining .fb_blank reference is
in acx565akm_backlight_init() in panel-sony-acx565akm.c; I was planning on
nuking that along with the other .fb_blank initialisers in a series removing
.fb_blank entirely from backlight_properties. I’ll add it as a fourth patch
for drm/panel if that makes things easier!
There will still be references to FB_BLANK constants since they’re used for
backlight_properties.power values. Would it make sense to rename those?

Stephen
