Set phy->sband_{2,5,6}g.sband.band to the correct enum value, otherwise the ieee80211_register_hw() will fail to register the device. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=218466 Signed-off-by: Bert Karwatzki <spasswolf@web.de> --- drivers/net/wireless/mediatek/mt76/mac80211.c | 3 +++ 1 file changed, 3 insertions(+) -- 2.39.2 When using linux-next-20240205 my mediatek wifi device failed to start. A bisection led to commit f04d2c247e0407 as the problem: https://bugzilla.kernel.org/show_bug.cgi?id=218466 After closer examination of the mt76 code it the problem was to to be the incomplete initialization of phy->sband_{2,5,6}g. The band field has to be set to not confuse the new mac80211 code. (the sband_2g structure was correctly initialized accidendly as NL80211_BAND_2GHZ is 0). Bert Karwatzki
