In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: free iio for atombios when driver shutdown
Fix below kmemleak when unload radeon driver:
unreferenced object 0xffff9f8608ede200 (size 512):
comm "systemd-udevd", pid 326, jiffies 4294682822 (age 716.338s)

iio was allocated in atom_index_iio() called by atom_parse(),
but it doesn't got released when the dirver is shutdown.
Fix this kmemleak by free it in radeon_atombios_fini().
