From 9b27adbced2455bfd7e5d1b76a7f151de3d25dec Mon Sep 17 00:00:00 2001 From: Jens Taprogge Date: Wed, 12 Sep 2012 14:55:24 +0200 Subject: [PATCH] Staging: ipack/bridges/tpci200: Remove side effects of tpci200_{request,free}_irq. Use the __tpci200_{set,clear}_mask routines to access control register. Do not overwrite flags unrelated to interrupt handling.
