Subject: [PATCH v4 0/3] I2C/SMBus: add support for Host Notify (in i2c_i801)

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().

Cheers,
Benjamin
