a=openpgp; fpr=8F88381DD5C873E4AE487DA5199BF1243632046A Newer Qualcomm platforms (sm8450+) successfully handle busy state and send the Command Completion after sending the Busy state. Older devices have firmware bug and can not continue after sending the CCI_BUSY state, but the command that leads to CCI_BUSY is already forbidden by the NO_PARTNER_PDOS quirk. Follow other UCSI glue drivers and drop special handling for CCI_BUSY event. Let the UCSI core properly handle this state.
