From 1181ed21a973f1a8c5a535276685cc09c43a246f Mon Sep 17 00:00:00 2001 From: Ian Munsie Date: Wed, 4 Feb 2015 19:10:38 +1100 Subject: [PATCH] cxl: Add missing return statement after handling AFU errror commit a6130ed253a931d2169c26ab0958d81b0dce4d6e upstream. We were missing a return statement in the PSL interrupt handler in the case of an AFU error, which would trigger an "Unhandled CXL PSL IRQ" warning. We do actually handle these type of errors (by notifying userspace), so add the missing return IRQ_HANDLED so we don't throw unecessary warnings.
