The later revision of v3 hw has added an function of interrupt coalesce according to time for PHY RX errors. We set the coalesce time to 1s. Then we print PHY RX errors count when PHY RX errors happen, and don't need to worry that there may be too much log prints. Besides, we use hisi_sas_phy.lock to protect error count value. Because we update them by calling phy_get_events_v3_hw(), which is also used by core driver (for get PHY events function). We relocate phy_get_events_v3_hw() to avoid a further declaration.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
