This patch was found using coccicheck with api/memdup.cocci, with memdup.cocci script slightly altered in the following way: @depends on patch@ expression from,to,size,flag; position p != {r1.p,r2.p}; @@ - to = \(kmalloc@p\|kzalloc@p\)(size,flag); + to = kmemdup(from,size,flag); - memcpy(to, from, size); Signed-off-by: Xenia Ragiadakou Signed-off-by: Greg Kroah-Hartman --- drivers/staging/wlan-ng/prism2sta.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'drivers/staging') diff --git a/drivers/staging/wlan-ng/prism2sta.c b/drivers/staging/wlan-ng/prism2sta.c index 428a9be25010..76374b220228 100644 --- a/drivers/staging/wlan-ng/prism2sta.c +++ b/drivers/staging/wlan-ng/prism2sta.c @@ -1122,8 +1122,7 @@ static void prism2sta_inf_hostscanresults(wlandevice_t *wlandev, kfree(hw->scanresults); - hw->scanresults = kmalloc(sizeof(hfa384x_InfFrame_t), GFP_ATOMIC); - memcpy(hw->scanresults, inf, sizeof(hfa384x_InfFrame_t)); + hw->scanresults = kmemdup(inf, sizeof(hfa384x_InfFrame_t), GFP_ATOMIC); if (nbss == 0) nbss = -1; -- cgit v1.2.3
