After 92b004d1aa9f367c372511ca0330f58216b25703 the logos disappeared on 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.
