Subject: [2/7 v3] usb: otg: Remove one unnecessary I2C read request.
Date: Wed, 16 Feb 2011 17:20:44 +0530 [thread overview]
Message-ID: <1297857049-27367-2-git-send-email-hemahk@ti.com> (raw)
In-Reply-To: <1297857049-27367-1-git-send-email-hemahk-l0cyMroinI0@public.gmane.org>
From: Kalliguddi, Hema <hemahk-l0cyMroinI0@public.gmane.org>
To get the ID status there was an I2C read transfer. Removed this I2C
read transfer as this info can be used from existing variable(linkstat).
