[ Upstream commit876b15d2c8] When unloading the call to pm_runtime_put_sync_suspend() will attempt to turn the GPU cores off, however panfrost_device_fini() will have turned the clocks off. This leads to the hardware locking up. Instead don't call pm_runtime_put_sync_suspend() and instead simply mark the device as suspended using pm_runtime_set_suspended(). And also include this on the error path in panfrost_probe().

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.
