From bc63f50cbb2a7bc5fbee694ce547c812c0b54f54 Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Sun, 28 Feb 2016 17:21:06 +0530 Subject: [PATCH] staging: wilc1000: Removed unused variables Variables pcgroup_encrypt_val,pccipher_group,pcwpa_version, hold different values at different stages of the execution of connect(), however they are not being used anywhere. Hence, the unused variables have been removed. This was done using Coccinelle. @@ type T; identifier i; constant c; @@ -T i; <... when != i -i = c; ...> Signed-off-by: Bhaktipriya Shridhar Signed-off-by: Greg Kroah-Hartman --- .../staging/wilc1000/wilc_wfi_cfgoperations.c | 18 ------------------ 1 file changed, 18 deletions(-) diff --git a/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c b/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c index 378c3505e2b0..d7048237b183 100644 --- a/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c +++ b/drivers/staging/wilc1000/wilc_wfi_cfgoperations.c @@ -665,9 +665,6 @@ static int connect(struct wiphy *wiphy, struct net_device *dev, u32 i; u8 u8security = NO_ENCRYPT; enum AUTHTYPE tenuAuth_type = ANY; - char *pcgroup_encrypt_val = NULL; - char *pccipher_group = NULL; - char *pcwpa_version = NULL; struct wilc_priv *priv; struct host_if_drv *pstrWFIDrv; @@ -711,11 +708,8 @@ static int connect(struct wiphy *wiphy, struct net_device *dev, memset(priv->WILC_WFI_wep_key_len, 0, sizeof(priv->WILC_WFI_wep_key_len)); if (sme->crypto.cipher_group != NO_ENCRYPT) { - pcwpa_version = "Default"; if (sme->crypto.cipher_group == WLAN_CIPHER_SUITE_WEP40) { u8security = ENCRYPT_ENABLED | WEP; - pcgroup_encrypt_val = "WEP40"; - pccipher_group = "WLAN_CIPHER_SUITE_WEP40"; priv->WILC_WFI_wep_key_len[sme->key_idx] = sme->key_len; memcpy(priv->WILC_WFI_wep_key[sme->key_idx], sme->key, sme->key_len); @@ -731,8 +725,6 @@ static int connect(struct wiphy *wiphy, struct net_device *dev, sme->key_idx); } else if (sme->crypto.cipher_group == WLAN_CIPHER_SUITE_WEP104) { u8security = ENCRYPT_ENABLED | WEP | WEP_EXTENDED; - pcgroup_encrypt_val = "WEP104"; - pccipher_group = "WLAN_CIPHER_SUITE_WEP104"; priv->WILC_WFI_wep_key_len[sme->key_idx] = sme->key_len; memcpy(priv->WILC_WFI_wep_key[sme->key_idx], sme->key, sme->key_len); @@ -749,25 +741,15 @@ static int connect(struct wiphy *wiphy, struct net_device *dev, } else if (sme->crypto.wpa_versions & NL80211_WPA_VERSION_2) { if (sme->crypto.cipher_group == WLAN_CIPHER_SUITE_TKIP) { u8security = ENCRYPT_ENABLED | WPA2 | TKIP; - pcgroup_encrypt_val = "WPA2_TKIP"; - pccipher_group = "TKIP"; } else { u8security = ENCRYPT_ENABLED | WPA2 | AES; - pcgroup_encrypt_val = "WPA2_AES"; - pccipher_group = "AES"; } - pcwpa_version = "WPA_VERSION_2"; } else if (sme->crypto.wpa_versions & NL80211_WPA_VERSION_1) { if (sme->crypto.cipher_group == WLAN_CIPHER_SUITE_TKIP) { u8security = ENCRYPT_ENABLED | WPA | TKIP; - pcgroup_encrypt_val = "WPA_TKIP"; - pccipher_group = "TKIP"; } else { u8security = ENCRYPT_ENABLED | WPA | AES; - pcgroup_encrypt_val = "WPA_AES"; - pccipher_group = "AES"; } - pcwpa_version = "WPA_VERSION_1"; } else { s32Error = -ENOTSUPP; -- 2.30.2
