Freescale i.MX53 and i.MX6 SoC's (detected on linux-3.12.37).
This happens because the fb_find_logo function is validly called
(initdata still not freed) AFTER newly introduced latecall
fb_logo_late_init.
Instead of stetting a logos_freed flag somewhere in lateinit, this patch
uses system_state==SYSTEM_BOOTING as indication for valid initdata.
The kernel init does free_initmem() call before setting the system_state
to SYSTEM_RUNNING, so there's a period of time when the logos are freed,
but the check in you patch does not catch it.
