From 344fa0bad6932204146d305607790340f2324a90 Mon Sep 17 00:00:00 2001 From: Amit Kucheria Date: Thu, 12 Dec 2019 16:08:14 +0530 Subject: drivers: thermal: tsens: Work with old DTBs In order for the old DTBs to continue working, the new interrupt code must not return an error if interrupts are not defined. Don't return an error in case of -ENXIO.
