Subject: [PATCH net-next 10/14] tg3: Add error reporting to tg3_phydsp_write()
Date: Mon, 2 Aug 2010 14:26:04 -0700 [thread overview]
Message-ID: <1280784368-4226-10-git-send-email-mcarlson@broadcom.com> (raw)
This patch adds error reporting to the tg3_phydsp_write() function and
converts a few more locations to use this function over the inlined
equivalent.
