6.9-stable review patch. If anyone has any objections, please let me know.

commit f01af3022d4a46362c5dda3d35dea939f3246d10 upstream.
"Failed to lock the clock" is an appropriate error message for clk_rate_exclusive_get() failing, but not for the clock running too fast for the driver's calculations.
Adapt the error message accordingly.
