Subject: [PATCH] musb_host: compare status for negative error values
Date: Mon, 30 May 2011 20:45:42 +0200	[thread overview]
Message-ID: <4DE3E5D6.207@freemail.hu> (raw)

From: Márton Németh <nm127@freemail.hu>

Variable d is a struct usb_iso_packet_descriptor. The status filed is usually
negative when an error happens.

This was not tested at all! I just found this while I was browsing the
code and it looked like a typo. Please verify and test it before aplying
this patch. If I was wrong, sorry about that.
