I don't think so. We just need to wait for (GMBUS_SATOER | GMBUS_HW_WAIT_PHASE). Why would we wait for HW_READY, too?
Just paranoia when looking at the read/write sequences and wondering how safe they were with 0-length read/writes. No real reason to suspect that the code is incorrect in any way. -Chris
