From ufshcd_transfer_req_compl():
Resetting interrupt aggregation counters first and reading the
DOOR_BELL afterward allows us to handle all the completed requests. In
order to prevent other interrupts starvation the DB is read once after
reset. The down side of this solution is the possibility of false
interrupt if device completes another request after resetting
aggregation and before reading the DB.
Prevent that ufshcd_intr() reports a false positive "Unhandled interrupt"
message if the above scenario is triggered.

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.
