Subject: [021/249] staging: rtl8723au: rtw_update_ht_cap23a(): Use correct

staging: rtl8723au: Eliminate struct HT_info_element
|
|
|
|
Yet another duplicate version of struct ieee80211_ht_operation

|
|
introduced a bad error, applying the wrong value as the mask when
|
|
determining the location of the 40MHz channel, effectively making it
|
|
always determining it as not present. This caused hangs and delays
|
|
when running in 40MHz channel mode.
|
|
|
|
This should get it right.
