=20=20=20=20
=20   Translate driver-api/phy.rst into Chinese.
=20=20=20=20
=20   commit d02aa181ee59 ("phy: Add devm_of_phy_optional_get() helper")

you can run git log .../mseal.rst, then copy the first commite
message as my format.

Let's=20adjust the order of sentences in the future, so that
the reading will be more smooth and the reviewer's life
will be easier.


BTW,

At this stage, Chinese is maintained in doc tree, so you
need to --to corbet@lwn.net

And also --cc alexs@kernel.org  dzm91@hust.edu.cn
