1. You may occasionally put more than 60 characters into text lines
   of such a change description.
   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.17-rc4#n638

2. Would you like to increase the application of scope-based resource management?
   https://elixir.bootlin.com/linux/v6.17-rc4/source/include/linux/device.h#L1180

3. How do you think about to append parentheses to the function name
   in the summary phrase?
