[ Upstream commit 45c8034db47842b25a3ab6139d71e13b4e67b9b3 ]
If clk_get_sys(..., "pll_d2_out0") fails, the clk_get_sys() call must be
undone.
Add the missing clk_put and a new 'put_pll_d_out0' label in the error
handling path, and use it.
Fixes: 0c921b6d4ba0 ("drm/tegra: dc: rgb: Allow changing PLLD rate on Tegra30+")
