Subject: fbdev/arcfb: Set FBINFO_VIRTFB flag
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=30b72c0bde93ae3001736b596cf94bfb47c5e159;p=linux.git

fbdev/arcfb: Set FBINFO_VIRTFB flag

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