Shang XiaoJing 0ae41323a8 drm/vc4: vec: Use pm_runtime_resume_and_get() in vc4_vec_encoder_enable()
Commit f0601ef863 ("drm/vc4: vec: Protect device resources after
removal") add fail path for vc4_vec_encoder_enable(), and will put
usage_counter only when pm_runtime_get_sync() succeeds. However,
pm_runtime_get_sync() will increment usage_counter even it failed. Fix
it by replacing it with pm_runtime_resume_and_get() to keep usage
counter balanced.

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.
