About boot time Tux logo with -EPROBE_DEFER

Hi

I want to ask you about boot time Tux logo.

For some reasons, current our video driver returns -EPROBE_DEFER when
probe timing, but logo init function doesn't care it.
Thus, our kernel can't have logo when boot time.

I think this is not only our issue, but general issue ?

Thus, I think logo init function should care about -EPROBE_DEFER
or something. In our quick hack, this issue was solved by below patch,
but I don't know this is OK.

So, how to solve this issue ? do you have nice idea ?
or can maintainer accept below patch ?

/* logo's are marked __initdata. Use __ref to tell
