From 72e3d4e557550d1f3df134773cb91db51860dd71 Mon Sep 17 00:00:00 2001 From: Sukwon Ryoo Date: Wed, 13 Mar 2019 15:32:09 +0900 Subject: [PATCH] [ERD][NEUS7920-135] [COMMON]chub: No remove sensorinfo in reset When something went wrong during os select, sensorinfo area is swiped out because of reset. So HAL can not get sensorlist. This patch makes IPC area set 0 except sensorinfo area.
