Hello Larry Finger,
The patch d76d65fd2695: "rtlwifi: fix broken VHT support" from Feb 1,
2016, leads to the following static checker warning:
drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series()
warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)'
drivers/net/wireless/realtek/rtlwifi/rc.c
135 if (sgi_20 || sgi_40 || sgi_80)
136 rate->flags |= IEEE80211_TX_RC_SHORT_GI;
137 if (sta && sta->ht_cap.ht_supported &&
138 ((wireless_mode == WIRELESS_MODE_N_5G) ||
139 (wireless_mode == WIRELESS_MODE_N_24G)))
140 rate->flags |= IEEE80211_TX_RC_MCS;
141 if (sta && sta->vht_cap.vht_supported &&
142 (wireless_mode == WIRELESS_MODE_AC_5G ||
143 wireless_mode == WIRELESS_MODE_AC_24G ||
144 wireless_mode == WIRELESS_MODE_AC_ONLY))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Not possible. sta_entry->wireless_mode is u8 and WIRELESS_MODE_AC_ONLY
is 0x100.
145 rate->flags |= IEEE80211_TX_RC_VHT_MCS;
146 }
147 }
regards,
dan carpenter
