Subject: kernel: ltq-ptm: do not write directly to dev->addr
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=598e058080b990cf59ff84d3d50b639f44f11614;p=openwrt%2Fstaging%2Flinusw.git

kernel: ltq-ptm: do not write directly to dev->addr

One is never to write to dev->addr directly. In 6.1 it will be a const and
with the newly enabled WERROR, we get a failing grade.

Lets fix this ahead of time.
