[PATCH] fbdev: iomove removal
Since no one is using the inbuf, outbuf of struct fb_pixmap I removed their use in the framebuffer console. The idea is instead move the pixmap functionality below the accelerated functions intead of on top as the way it is now. If there is no objection please apply. This is against Linus latestr GIT tree. Thank you. Signed-off-by: James Simmons <jsimmons@www.infradead.org> Cc: "Antonino A.
