commit 3c978492c333f0c08248a8d51cecbe5eb5f617c9 upstream.
The retry loop continues to iterate until the count reaches 30, even after
receiving the correct value. Exit loop when a non-zero value is read.
Fixes: 4ca10f3e31 ("scsi: mpt3sas: Perform additional retries if doorbell read returns 0")

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.
