unregister_framebuffer — releases a frame buffer device
int unregister_framebuffer ( | struct fb_info * | fb_info); |
Unregisters a frame buffer device fb_info.
Returns negative errno on error, or zero for success.
This function will also notify the framebuffer console to release the driver.
This is meant to be called within a driver's module_exit
function. If this is called outside module_exit, ensure
that the driver implements fb_open and fb_release to
check that no processes are using the device.
