But actually I am thinking to totally remove this function and use more conventional fb_get_mode() in its places. But if i do so then the boot parameters will change. Currently it is like vga=sm712fb:0x301 but if i change it to use fb_get_mode() then the boot parameters will change to vga=sm712fb:640x480@60-8 , and that is why I am hesitating. But it will be more conventional to what all framebuffer drivers follows. > > > > > > > Hm... That's a good question. > > > > I suspect we should just go with fb_get_mode() and do it quickly.

Perhaps Greg has an opinion? regards, dan carpenter
