Commitfc44449411("scsi: mpi3mr: HDB allocation and posting for hardware and firmware buffers") added the spinlock trigger_lock to the struct mpi3mr_ioc. However, spin_lock_init() call was not added for it, then the lock does not work as expected. Also, the kernel reports the message below when lockdep is enabled. INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe you didn't initialize this object before use? To fix the issue and to avoid the INFO message, add the missing spin_lock_init() call.

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 reStructuredText 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.
