Checking for rate->count not being zero is not enough. Allowing a rate with negative index leads to memory corruption in ath_debug_stat_rc(). One consequence of the bug is discussed at https://bugzilla.redhat.com/show_bug.cgi?id=768639 Signed-off-by: Pavel Roskin Cc: stable@vger.kernel.org Signed-off-by: John W.
