Subject: [PATCH RFC 0/3] treewide: remove open coded SMBus block transfers

The bigger picture is that I want to extend the maximum block length for
SMBus block transfers from 32 (SMBus2) to 255 (SMBus3). That needs some
cleanups and refactoring first. To make that easier, it would be helpful
if all in-kernel users would call the helper functions of the I2C core
for SMBus block transfers and not open code it via the generic
smbus_xfer.

This series converts the three users doing that. I don't have the
hardware, so these patches are only build tested. Please let me know
what you think.
