[PATCH 1/1] mfd: Simplify IRQ domain registration code in STMPE

From: Lee Jones
Date: Fri Nov 23 2012 - 10:19:23 EST


Historically, a driver would have to decide whether it required
a Linear or Legacy IRQ domain when registering one. This can end
up as quite a lot of code. A new Simple call now exists which
simplifies this process. Let's make use of it here.
