3.2.60-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Olof Johansson <[email protected]> commit ce78cc071f5f541480e381cc0241d37590041a9d upstream. Don't unmark the device as suspended until after it's been re-setup. The main race would be w.r.t. an i2c driver that gets resumed at the same time (asyncronously), that is allowed to do a transfer since suspended is set to 0 before reinit, but really should have seen the -EIO return instead.
