Accessing a host controller register after the host controller has

I am not clear on the offending condition, particularly the term "hibernation" used in this context. In the function ufshcd_uic_pwr_ctrl() where you are making the change, the host controller is fully active at this point, right?
Please help me clarify the issue.

Thanks, Bao
