From 595644ccdc0efb128458f91878f099719786370a Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Tue, 27 Feb 2018 16:45:25 -0800 Subject: [PATCH] soc: qcom: wcnss_ctrl: Fix increment in NV upload hdr.len includes both the size of the header and the fragment, so using this when stepping through the firmware causes us to skip 16 bytes every chunk of 3072 bytes; causing only the first fragment to actually be valid data. Instead use fragment size steps through the firmware blob.
