Subject: [PATCH v2 0/2] i2c: Don't assume bus nr 0 if none was specified
Changes since v1:
- Dropped reduntant i2c-octeon change
i2c controller drivers used to assume bus number 0 when none (-1) was
specified.
This worked on non-device tree systems, where one could explicitly
specify bus number via platform data. On DT-enabled systems bus
number is always -1.
This patchset reworks few remaining drivers to use dynamic bus
allocation when no id has been provided.
[ I've found out this when I've tried to instantiate more than one
i2c-gpio instance on DT-enabled system. I've, hopefully, fixed few
other drivers too. ]

i2c-pxa: Drop leftover comment
i2c: Dynamically assign adapter id if it wasn't explictly specified
