[PATCH v3 4/5] soc/tegra: pmc: Use of_clk_get_parent_count() instead of open coding

[Stephen Boyd]

Quoting Geert Uytterhoeven (2018-04-18 07:50:04)
> As of_clk_get_parent_count() returns zero on failure, while
> of_count_phandle_with_args() might return a negative error code, this
> also fixes the issue of possibly using a very big number in the
> allocation below.
