From: Thomas Meyer <[email protected]> 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 <[email protected]> --- diff -u -p a/drivers/staging/rtl8192e/rtllib_softmac.c b/drivers/staging/rtl8192e/rtllib_softmac.c --- a/drivers/staging/rtl8192e/rtllib_softmac.c 2011-11-07 19:38:11.780313813 +0100 +++ b/drivers/staging/rtl8192e/rtllib_softmac.c 2011-11-08 09:40:07.649215930 +0100 @@ -3048,10 +3048,9 @@ void rtllib_softmac_init(struct rtllib_d ieee->state = RTLLIB_NOLINK; for (i = 0; i < 5; i++) ieee->seq_ctrl[i] = 0; - ieee->pDot11dInfo = kmalloc(sizeof(struct rt_dot11d_info), GFP_ATOMIC); + ieee->pDot11dInfo = kzalloc(sizeof(struct rt_dot11d_info), GFP_ATOMIC); if (!ieee->pDot11dInfo) RTLLIB_DEBUG(RTLLIB_DL_ERR, "can't alloc memory for DOT11D\n"); - memset(ieee->pDot11dInfo, 0, sizeof(struct rt_dot11d_info)); ieee->LinkDetectInfo.SlotIndex = 0; ieee->LinkDetectInfo.SlotNum = 2; ieee->LinkDetectInfo.NumRecvBcnInPeriod = 0; _______________________________________________ devel mailing list [email protected] http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
