[PATCH] of/irq: add empty irq_of_parse_and_map() for non-dt builds

[Thomas Abraham]

Add a empty irq_of_parse_and_map() that returns 0 for non-dt builds and
avoid having #ifdef CONFIG_OF around all calls to irq_of_parse_and_map().

Screwed up the lkml address, so just adding it back...

As replied to on original patch, this isn't necessary.  Just merge it
via the Samsung tree since you've already got my acked-by on it.

Thanks. I will do that change which you have suggested and take it
through the Samsung tree. But I was thinking that if it goes through
your tree, there would be less chances of a merge conflict in
include/linux/of_irq.h, a file that might see updates from other
sources.

Thanks,
Thomas.

Hmmm... is this going to be merged for v3.4 or v3.5?  If it is v3.5,
then yes it probably does need to go through my tree since there may
be others that need to pull it into their trees.  I was thinking that
you needed this immediately.
