Hi, this is the v4 of this patch series which fixes the race we discovered this week when accessing the registers in i2c_i801. Compared to v3, i2c_handle_smbus_host_notify can now be called in a non sleeping thread because a worker will be spawn later on. That also means that we need to allocate the worker and some other structures, so I introduced i2c_setup_smbus_host_notify().
