Subject: wl12xx: move pspoll_work into wlvif
X-Git-Tag: upstream/snapshot3+hdmi~8450^2~44^2~203^2~76
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=252efa4f978a2901039fffc934060fb8ccf82ac7;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

wl12xx: move pspoll_work into wlvif

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