[PATCH 5/6] drm/tegra: rgb: Fix missing clk_put() in the error handling paths of tegra_dc_rgb_probe()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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+")
