Subject: [PATCH v9 11/15] media: mtk-vcodec: dec: Remove mtk_vcodec_release_dec_pm
Date: Fri, 12 Nov 2021 18:55:05 +0800	[thread overview]
Message-ID: <20211112105509.12010-12-yong.wu@mediatek.com> (raw)
In-Reply-To: <20211112105509.12010-1-yong.wu@mediatek.com>

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.
