From: paulfax Date: Tue, 27 Jan 2009 08:44:07 +0000 (-0600) Subject: powerpc/cpm2: Fix set interrupt type X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=7f3ea17f316577e31db868f720ac575c74d20163;p=linux-2.6-omap-h63xx.git powerpc/cpm2: Fix set interrupt type This is a simple change to correct problems when using set_irq_type on platforms using CPM2. This code corrects the problem on most platform but may have issues on 8272 derived platforms for some interrupts. On 8272 PC2 & 3 are missing and PC 23 & 29 are added, which this patch does not address.
