If 'dmam_alloc_attrs()' fails, we must go through the error handling code,

I'm also puzzled by the 'framebuffer_alloc()' call a few lines above.
'ret' is known to be 0 at this point. I guess that -ENOMEM should also be
returned.
Yes, moreover the "failed:" error path is incomplete (please take
a look at au1200fb_drv_remove() for comparison) and needs to be fixed.
Could you please take care of it?
I will try, but be indulgent :)
My understanding of the code is that they are several issues all related
to this error handling path (double free, missing memory release,
invalid irq release...)
I will try to sort it out, but my first tries will likely be incomplete
and/or broken.
