Subject: [PATCH] misc fixes to 11-pre5
Date: Wed, 15 Nov 2000 17:29:05 -0500 (EST)	[thread overview]
Message-ID: <Pine.GSO.4.21.0011151715060.8442-100000@weyl.math.psu.edu> (raw)

	* baycom_epp: yet another missed x86_capability instance.
	* soundmodem/sm.h: ditto.
	* wan/comx.c: fixed typo in call of remove_proc_entry() (the second
argument is proc_dir_entry *, not **)
	* scsi/gdth.c::gdth_flush() had a path with use of uninitialized
variable:

	/* bar is not initialized */
	if (foo)
		bar = baz();
	if (foo && bar) {
		/* code that doesn't change foo or bar */
	}
	/* If foo was NULL we have random junk in bar */
	if (bar)
		quux(bar);
	if (foo)
		barf(foo);
	return;

Fixed variant:

	if (!foo)
		return;
	bar = baz();
	if (bar) {
		/* same code */
		quux(bar);
	}
	barf(foo);
	return;

- same, except that we don't do bogus if (bar) quux(bar); in case if bar
had never been initialized.

	Please, apply. And yes, it really passes compile ;-/
								Cheers,
									Al
