Subject: [PATCH] video/logo: prevent use of logos after they have been freed

Hi,

The fbdev logo seems to be rather messed up when deferred probing is happening.
This is a quick fix for the problem.

The code in the logo.c is quite scary, using __init_refok to silence warnings
about accessing __initdata from non-init context.

Another option would be to make the logos not __initdata, but I think that's
not acceptable.

Any ideas for a nicer way to fix this issue?

 Tomi
