[PATCH 0/3] i2c: Relax requirement for I2C Device ID tables

[Lee Jones]

Hi Wolfram,

After this patch-set, it should become possible to start stripping out
those unnecessary I2C Device ID tables that are currently lurking around,
mostly redundantly.  Firstly, we create a look-up function whose job it
is to match I2C device name to a Device Tree node.  Then we add some
extra protection in i2c_match_id(), so that we can call the function with
a NULL parameter. This in turn aids to the elegance of the final change
which relaxes the requirement of a populated .id_table.

Kind regards,
Lee
