Subject: Re: [PATCH] rtc-ds1307: True SMBus compatibility

Here is an updated patch for rtc-ds1307 that allows the driver to work
with SMBus controllers like nforce2 that do not support i2c block
transfers.  The driver now checks the capabilities of the controller and
emulates the block transfers with SMBus byte transfers only if
necessary.
