Subject: usbnet: smsc95xx: fix suspend failure
From: Ming Lei <[email protected]>
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).
