memory: tegra: Correct debugfs clk rate-range on Tegra124
Correctly set clk rate-range if number of available timings is zero. This fixes noisy "invalid range [4294967295, 0]" error messages during boot. Fixes: 6b9acd935546 ("memory: tegra: Refashion EMC debugfs interface on Tegra124") Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
