Subject: wl12xx: move dev_hlid into wlvif
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=afaf8bdb2b08bbf493b03757243821df72b26c53;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

wl12xx: move dev_hlid into wlvif

move dev_hlid into the per-interface data, rather than
being global.
