The code below shows the same pattern, and thus should perhaps be fixed in the same way. This is not tested and clearly changes the semantics, so it is only something to consider. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @@ expression E1,E2; @@ ( !E1 & !E2 | - !E1 & E2 + !(E1 & E2) ) // Signed-off-by: Julia Lawall --- diff -u -p a/drivers/net/wireless/iwlwifi/iwl-4965.c b/drivers/net/wireless/iwlwifi/iwl-4965.c --- a/drivers/net/wireless/iwlwifi/iwl-4965.c 2008-02-05 20:56:01.000000000 +0100 +++ b/drivers/net/wireless/iwlwifi/iwl-4965.c 2008-02-26 08:09:12.000000000 +0100 @@ -4589,7 +4589,7 @@ static u8 iwl4965_is_fat_tx_allowed(stru if (sta_ht_inf) { if ((!sta_ht_inf->ht_supported) || - (!sta_ht_inf->cap & IEEE80211_HT_CAP_SUP_WIDTH)) + (!(sta_ht_inf->cap & IEEE80211_HT_CAP_SUP_WIDTH))) return 0; } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
