Hi, Po wen and Peter


I must give this patch Ack, because:

1. “fHPBReset Flag” can be sent in both host control mode and device
control mode. “buffer id=3 HpbWriteBuffer” can only be sent in device
control mode.

2. “fHPBReset Flag” inactivate all the regions for the whole device.
“buffer id=3 HpbWriteBuffer” can only inactivate all the regions for
this LUN. The LUN is written in the UPIU header.

In the ufshpb_init, we have set fHPBReset Flag. here doesn't need to
issue “buffer id=3 HpbWriteBuffer” in the case of device mode.

Regarding the reset flow issue we are talking about, I will submit a
fix.
