Subject: [PATCH v2] media: mediatek: vcodec: mtk_vcodec_dec_hw: Use devm_pm_runtime_enable()

Convert pm_runtime_enable() to the managed version, and clean up error
handling and unnecessary .remove() callback accordingly.

Signed-off-by: Fei Shao <[email protected]>

Changes in v2:
Use devm_pm_runtime_enable() per suggestion from the previous thread:

This patch no longer applies. Can you make a v3?

Sorry, you can ignore this. I now realize that this was a v2 of

https://patchwork.linuxtv.org/project/linux-media/patch/20230510233117.1.I7047714f92ef7569bd21f118ae6aee20b3175a92@changeid/

I had that v1 applied, so obviously this v2 would fail to apply. After dropping
that v1 patch it now applies cleanly.

Ack, many thanks.
BTW, besides the review tags (appreciation to all), would you mind
adding this tag also as I missed it in the beginning?
