Smatch complains:
data_tx.c:37 wfx_get_hw_rate() warn: constraint '(struct ieee80211_supported_band)->bitrates' overflow 'band->bitrates' 0 <= abs_rl '0-127' user_rl '' required = '(struct ieee80211_supported_band)->n_bitrates'
23 struct ieee80211_supported_band *band;
24
25 if (rate->idx < 0)
26 return -1;
27 if (rate->flags & IEEE80211_TX_RC_MCS) {
28 if (rate->idx > 7) {
29 WARN(1, "wrong rate->idx value: %d", rate->idx);
30 return -1;
31 }
32 return rate->idx + 14;
33 }
34 // WFx only support 2GHz, else band information should be retrieved
35 // from ieee80211_tx_info
36 band = wdev->hw->wiphy->bands[NL80211_BAND_2GHZ];
37 return band->bitrates[rate->idx].hw_value;
Add a simple check to make Smatch happy.
