[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon
According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant. The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.
Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank. For drivers that do, they can fill up this field with their own
version.
The end result is a smaller code size. And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.
