From 821f664644c2da9e1a51e36751abedf49d4332e0 Mon Sep 17 00:00:00 2001 From: Samu Onkalo Date: Fri, 22 Oct 2010 07:57:26 -0400 Subject: [PATCH] hwmon: lis3: Update coordinates at polled device open Call input device poll function at device open to refresh coordinates immediately. This is needed for the case where poll interval is set to zero and coordinate updates happens purely under interrupt control.
