Subject: [U-Boot] [PATCH 3/3] tegra: usb: fix wrong error check
Date: Tue, 29 May 2012 23:47:13 +0200 [thread overview]
Message-ID: <1338328033-8597-3-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1338328033-8597-1-git-send-email-dev@lynxeye.de>
Just stumbled upon this, while looking through the usb code. loop_count
runs down from 10000, so the correct condition to error out is ==0.
