Bug 58831

Just got this compiling from commit 72de4c63e5ebe8e4054ea800d7a8d4b3f033caf2:

drivers/gpu/drm/qxl/qxl_fb.c:162:15: error: variable ‘qxl_defio’ has initializer but incomplete type
drivers/gpu/drm/qxl/qxl_fb.c:163:2: error: unknown field ‘delay’ specified in initializer
drivers/gpu/drm/qxl/qxl_fb.c:163:2: warning: excess elements in struct initializer [enabled by default]

drivers/gpu/drm/qxl/qxl_fb.c:456:6: error: ‘struct fb_info’ has no member named ‘fbdefio’

Don't think it counts as a regression as it's new.
