NAME

unregister_framebuffer - releases a frame buffer device

SYNOPSIS

int unregister_framebuffer(struct fb_info * fb_info);

ARGUMENTS

fb_info

frame buffer info structure

DESCRIPTION

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.
