Colin Ian King e3e64f3f99 usb: isp1760: check for null return from kzalloc ... isp1760_ep_alloc_request allocates a structure with kzalloc without checking for NULL and then returns a pointer to one of the structure fields. As the field happens to be the first in the structure the caller can properly check for NULL, but this is risky if the structure layout is changed later. Add an explicit NULL check for the kzalloc return value Detected with smatch static analysis: drivers/usb/isp1760/isp1760-udc.c:816 isp1760_ep_alloc_request() error: potential null dereference 'req'. (kzalloc returns null) [ thanks to Laurent Pinchart for improved commit message ] Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2015-06-08 14:25:04 -07:00
