Alex Elder d75286852b greybus: add write retry support for i2c ... It is expected that i2c writes may fail, and in that case the driver simply retries some number of times before actually treating it as a failure. Define a GB_OP_RETRY status, which is interpreted by the i2c driver as an indication a retry is in order. We just translate that into an EAGAIN error passed back to the i2c core.
