From a42ccdc14de388a35ad0e8057543369351395eb9 Mon Sep 17 00:00:00 2001 From: Anand Gadiyar Date: Sun, 21 Nov 2010 23:23:41 +0530 Subject: [PATCH] usb: ehci-omap: add helpers for checking port mode Introduce helper functions to test port mode. These checks are performed in several places in the driver, and these helpers improve readability.
