From b66acb63f5593ac11e39ab1cf17e1f987bc5ff9c Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 10 Dec 2010 20:42:59 +0000 Subject: [PATCH] Blackfin: bf54x: don't ack GPIO ints when unmasking them When unmasking a GPIO interrupt on a BF54x part, the code will implicitly ack any pending interrupts. This is not what unmasking should do and can cause people to miss interrupts from their devices, so punt the code.
