--------------------------------

[ Upstream commit b78870e7 ]

Ensure tegra_host member "curr_clk_rate" holds the actual clock rate
instead of requested clock rate for proper use during tuning correction
algorithm. Actual clk rate may not be the same as the requested clk
frequency depending on the parent clock source set. Tuning correction
algorithm depends on certain parameters which are sensitive to current
clk rate. If the host clk is selected instead of the actual clock rate,
tuning correction algorithm may end up applying invalid correction,
which could result in errors
