From: Thomas Meyer <thomas@xxxxxxxx> Use kzalloc rather than kmalloc followed by memset with 0 This considers some simple cases that are common and easy to validate Note in particular that there are no ...s in the rule, so all of the matched code has to be contiguous The semantic patch that makes this change is available in scripts/coccinelle/api/alloc/kzalloc-simple.cocci. More information about semantic patching is available at http://coccinelle.lip6.fr/ Signed-off-by: Thomas Meyer <thomas@xxxxxxxx> --- diff -u -p a/drivers/staging/rtl8192e/rtllib_crypt_ccmp.c b/drivers/staging/rtl8192e/rtllib_crypt_ccmp.c --- a/drivers/staging/rtl8192e/rtllib_crypt_ccmp.c 2011-11-07 19:38:11.773647045 +0100 +++ b/drivers/staging/rtl8192e/rtllib_crypt_ccmp.c 2011-11-08 09:40:09.422573035 +0100 @@ -63,10 +63,9 @@ static void *rtllib_ccmp_init(int key_id { struct rtllib_ccmp_data *priv; - priv = kmalloc(sizeof(*priv), GFP_ATOMIC); + priv = kzalloc(sizeof(*priv), GFP_ATOMIC); if (priv == NULL) goto fail; - memset(priv, 0, sizeof(*priv)); priv->key_idx = key_idx; priv->tfm = (void *)crypto_alloc_cipher("aes", 0, CRYPTO_ALG_ASYNC); _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
