[PATCH 05/14] clk: tegra: Init cfg structure in _get_pll_mnp

[Peter De Schrijver]

Not all fields are read from the hw depending on the PLL type. Make sure
the other fields are 0 by clearing the structure beforehand to prevent
users such as the rate re-calculation code from using bogus values.

Based on work by  Alex Frid <afrid@xxxxxxxxxx>
