[PATCH 3/6] powerpc: Remove get_irq_desc()
Michael Ellerman
michael at ellerman.id.au
Wed Oct 14 16:44:51 EST 2009
get_irq_desc() is a powerpc-specific version of irq_to_desc(). That
is reason enough to remove it, but it also doesn't know about sparse
irq_desc support which irq_to_desc() does (when we enable it).
