From 6ee7c0a0a5003abd4afd724f5c2f654fe7328c0a Mon Sep 17 00:00:00 2001 From: Matt Carlson Date: Mon, 2 Aug 2010 11:26:04 +0000 Subject: [PATCH] tg3: Add error reporting to tg3_phydsp_write() 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.
