[PATCH v9 11/15] media: mtk-vcodec: dec: Remove mtk_vcodec_release_dec_pm

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

 



After this patchset, mtk_vcodec_release_dec_pm has only one line.
then remove that function. Use pm_runtime_disable directly instead.

For symmetry, move the pm_runtime_enable out from
mtk_vcodec_init_dec_pm, then mtk_vcodec_init_dec_pm only operate for
the clocks, rename it from the _pm to _clk.

No functional change.
