fbdev: kill fb_rotate
The fb_rotate method in struct fb_ops is never actually invoked, and it's been that way in the entire history of git (in fact, the last occurrence of the string '->fb_rotate' vanished over 10 years ago, with b4d8aea6d6, and that merely tested whether the callback existed). So remove some dead code and make struct fb_obs a little smaller. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
