+Subject: powerpc/powernv/opal-dump : Use IRQ_HANDLED instead of numbers in
+ interrupt handler
+
+From: Mukesh Ojha <mukesh02@linux.vnet.ibm.com>
+
+[ Upstream commit b29336c0e1785a28bc40a9fd47c2321671e9792e ]
+
+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.
