  Qcom UFS hosts, with HW ver 5, can only support up to HS-G5 Rate-A due to
HW limitations. If the HS-G5 PHY gear is used, update host_params->hs_rate
to Rate-A, so that the subsequent power mode changes shall stick to Rate-A.

Is this 'else' part really needed? Since there wouldn't be any 2nd init, I think
we can skip that.

We need it because, even there is only one init, if a UFS3.1 device is 
attached, phy_gear is given as UFS_HS_G4 in ufs_qcom_set_phy_gear(), 
hence we need to put the UFS at HS-G4 Rate B, not Rate A.

Thanks,

But the default hs_rate is PA_HS_MODE_B only and the else condition would be not
needed for the 1st init.

You are right, but still we need this in case the UFS device version is 
not populated, meaning dual init can also happen to SM8550. We need to 
apply the right hs_rate in case the 2nd init asks for HS_G4.

Hmm, yeah I missed that corner case. This is fine.
