[PATCH] fbdev: update info->cmap when setting cmap from user-/kernelspace.
The fb_info struct, as defined in include/linux/fb.h, contains an element
that is supposed to hold the current color map:
struct fb_cmap cmap; /* Current cmap */
This cmap is currently never updated when either fb_set_cmap() or
fb_set_user_cmap() are called. As a result, info->cmap contains the
default cmap that was set by a device driver/fbcon and a userspace
application using the FBIOGETCMAP ioctl will not always get the *currently*
used color map.
The patch fixes this by making sure the cmap is copied to info->cmap after
it is set correctly. It moves most of the code that is responsible for
setting the cmap to fb_set_cmap() and out of fb_set_user_cmap() to avoid
code-duplication.
