As is, that'd print:
"<level>dev_driver_string(&wiphy->dev) dev_name(&wiphy->dev): wiphy_name(wiphy): " fmt, ##args
for instance:
[ 41.261941] ieee80211 phy0: phy0: Selected rate control algorithm 'minstrel_ht'
ie: redundant.
wiphy_name(wiphy) is an inline for dev_name(&wiphy->dev)
So it's appropriate to use:
#define wiphy_<level>(wiphy, fmt, arg...) dev_<level>(&wiphy->dev, fmt, ##arg)
and the output becomes:
[ 41.261941] ieee80211 phy0: Selected rate control algorithm 'minstrel_ht'
