Hi,
shouldn't it be u32 instead of u64? Please correct me if I'am wrong.

Example:
cfg80211_ready_on_channel(wk->sdata->dev, (u32)wk, wk->chan,
		wk->chan_type, wk->remain.duration, GFP_KERNEL);
instead of:
cfg80211_ready_on_channel(wk->sdata->dev, (u64)wk, wk->chan,
		wk->chan_type, wk->remain.duration, GFP_KERNEL);

I wish you all a happy new year!
