Subject: fbdev/vfb: Set FBINFO_VIRTFB flag
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=63994d486c9fb5e780dabb0571c607c25d485421;p=linux.git

fbdev/vfb: Set FBINFO_VIRTFB flag

The vfb driver operates on system memory. Mark the framebuffer
accordingly. Helpers operating on the framebuffer memory will test
for the presence of this flag.
