[cppcheck] resource leak xf86Configure.c

[Martin Ettl]

Hi friends,

here is another issue (spotted out by cppcheck, a static code analysis tool).

It prints the following warning:

../xfree86/common/xf86Configure.c,266,possible error,Resource leak: fd

Take a look into file xf86Configure.c at line 266:

...
	fd = open("/dev/wsmouse", 0);
	if (fd > 0) {
	    DFLT_MOUSE_DEV = "/dev/wsmouse";
	    DFLT_MOUSE_PROTO = "wsmouse";
	    close(fd);
	} else {
	    ErrorF("cannot open /dev/wsmouse\n");
	}
...

As you can see, the if()-statement is wrong because open returns the filepointer or, in case of an error -1 !! See the attached patch that corrects that issue.

Best regards

Martin
