From 01625cc5e65f420dbea57f7de6b9552a0f807a84 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Wed, 15 Feb 2017 14:00:41 -0800 Subject: remoteproc: qcom: mdt_loader: Use signed type for offset In the transition from using rproc_da_to_va(), the type of the load offset became unsigned. This causes the subsequent check to let negative values less than p_memsz + mem_size through and we write outside of the buffer. Change the type back to a signed value to catch this.
