3.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ming Lei <ming.lei@xxxxxxxxxxxxx> commit 7643721471117d5f62ca36f328d3dc8d84af4402 upstream. The three below functions: smsc95xx_enter_suspend0() smsc95xx_enter_suspend1() smsc95xx_enter_suspend2() return > 0 in case of success, so they will cause smsc95xx_suspend() to return > 0 and cause suspend failure. The bug is introduced in commit 3b9f7d(smsc95xx: fix error handling in suspend failure case).
