Haotian Zhang dc5db35073 soc: qcom: smem: fix hwspinlock resource leak in probe error paths
The hwspinlock acquired via hwspin_lock_request_specific() is not
released on several error paths. This results in resource leakage
when probe fails.

Switch to devm_hwspin_lock_request_specific() to automatically
handle cleanup on probe failure. Remove the manual hwspin_lock_free()
in qcom_smem_remove() as devm handles it automatically.

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.
