Subject: Re: [PATCH] postfix decrement error in ipw2100_start_adapter(); drivers/net/wireless/ipw2100.c
Date: Mon, 05 Nov 2007 23:55:02 +0100	[thread overview]
Message-ID: <472F9F46.3030604@tiscali.nl> (raw)
In-Reply-To: <472E671F.80907@tiscali.nl>

It appears there was another. The patch below includes both fixes.
--
If i reaches zero, the loop ends, but the postfix decrement subtracts it to -1.
Testing for 'i == 0', later in the function, will not fulfill its purpose.
