Subject: [PATCH 4.14 435/496] soc: qcom: wcnss_ctrl: Fix increment in NV upload
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bjorn Andersson <bjorn.andersson@...aro.org>
[ Upstream commit 90c29ed7627b6b4aeb603ee197650173c8434512 ]
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.
