From b29336c0e1785a28bc40a9fd47c2321671e9792e Mon Sep 17 00:00:00 2001 From: Mukesh Ojha Date: Mon, 20 Feb 2017 18:52:11 +0530 Subject: [PATCH] powerpc/powernv/opal-dump : Use IRQ_HANDLED instead of numbers in interrupt handler Fixes: 8034f715f ("powernv/opal-dump: Convert to irq domain") Converts all the return explicit number to a more proper IRQ_HANDLED, which looks proper incase of interrupt handler returning case. Here, It also removes error message like "nobody cared" which was getting unveiled while returning -1 or 0 from handler.
