X-Git-Tag: 2.1b_release~189
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7673a49c8e0d5b524ebf3619dc9fc6ab14c9f7d6;p=kernel%2Fkernel-mfld-blackbay.git

gfx: drv: Move stolen vram iounmap() into gtt code

The stolen memory is ioremap()ed in gtt init. Move the iounmap to the
gtt takedown function instead of doing it from the fbdev compatibility
code.
