From 6e3e49bbfe67b717d5a9a0540fa8fad5dead6b14 Mon Sep 17 00:00:00 2001 From: Jeffrey Hugo Date: Fri, 12 Feb 2021 17:40:14 -0700 Subject: bus: mhi: core: Use current ee in intvec handler for syserr The intvec handler stores the caches ee in a local variable for use in processing the intvec. When determining if a syserr is a fatal error or not, the intvec handler is using the cached version, when it should be using the current ee read from the device. Currently, the device could be in the PBL ee as the result of a fatal error, but the cached ee might be AMSS, which would cause the intvec handler to incorrectly signal a non-fatal syserr.
