Currently, mhi_process_data_event_ring()/mhi_process_ctrl_ev_ring() APIs are ringing DB even if there are no ring elements to process. This could cause the device to process the DB event in the absence of ring elements. So to avoid this unnecessary device processing, let's ring event DB only if there are any ring elements to process.

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.
