Suraj Jitindar Singh	d0226d315d	powerpc/opal: Add inline function to get rc from an ASYNC_COMP opal_msg ... An opal_msg of type OPAL_MSG_ASYNC_COMP contains the return code in the params[1] struct member. However this isn't intuitive or obvious when reading the code and requires that a user look at the skiboot documentation or opal-api.h to verify this. Add an inline function to get the return code from an opal_msg and update call sites accordingly.

Neelesh Gupta	470834508f	i2c: Driver to expose PowerNV platform i2c busses ... The patch exposes the available i2c busses on the PowerNV platform to the kernel and implements the bus driver to support i2c and smbus commands. The driver uses the platform device infrastructure to probe the busses on the platform and registers them with the i2c driver framework.
