I am currently letting FlexeLint loose on the kernel again, and I have
turned my attention to a new warning from it:
_
return (err);
../../../dev/usb/usb_subr.c 604 Warning 548: else expected
Initally I ignored these warnings because the couple of them which
I looked at were actually ok, but now that I looked through all of
them I uncovered a couple of bugs which all follow the same pattern,
which I think I can best illustrate by quoting a randomly chosen
case:
#ifdef USB_DEBUG
#define DPRINTF(x) if (usbdebug) logprintf x
#define DPRINTFN(n,x) if (usbdebug>(n)) logprintf x
extern int usbdebug;
#else
#define DPRINTF(x)
#define DPRINTFN(n,x)
#endif
[...]
if (index == USB_UNCONFIG_INDEX) {
/* We are unconfiguring the device, so leave unallocated. */
DPRINTF(("usbd_set_config_index: set config 0\n"));
err = usbd_set_config(dev, USB_UNCONFIG_NO);
if (err)
DPRINTF(("usbd_set_config_index: setting config=0 "
"failed, error=%s\n", usbd_errstr(err)));
return (err);
}
Please be more careful.
