pm_runtime_get_sync() may increment the runtime PM usage count even if the resume fails, which requires an explicit pm_runtime_put_noidle() to balance it. This driver ignored the return value, risking a usage-count leak on resume failure. Replace it with pm_runtime_resume_and_get(), which returns 0 on success and a negative errno on failure, and only increments the usage count on success. This simplifies the error path and avoids possible leaks. Also check for errors explicitly with `if (ret < 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 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.
