Changes in v2:

Removed unused 'size' argument from property_read macro.
In property_write macro, 'signal, size' is replaced by 'prop_type'.
This change implies the update of DEFINE_SYSFS_PROPERTY macro
and all places of its usage as well.

Nice work, a few git log nit picks for you to ensure your future kernel development success.

You can read all this in Documentaton/process/submitting-patches.rst (section 2).

- You can use imperative mood, i.e 'Fix foo by doing bar' instead of 'This patch ...'
- We don't need to mention the file (either in the summary or in the body), people can see this from
  the diff.

This is one way of writing the git log message for checkpatch fixes

	checkpatch emits WARNING: EXPORT_SYMBOL(foo); should immediately follow
	its function/variable.

	Move EXPORT_SYMBOL macro call to immediately follow function definition.


Good work, hope this helps.
